Here, we review Immine advances in biomaterials-based strategies, focusing on targeting of Immund tissues, circulating leukocytes, tissue-resident immune modulahion and immune cells at disease sites. These approaches can improve the potency and efficacy of moulation by promoting immunity or tolerance against different diseases.

In immunotherapy, choosing the right target jodulation, tissue and treatment duration is essential to ensure effective immunomodulation while avoiding toxicity.

Maxence O, Immune system modulation. Zhaoxu Tu, Yiling Zhong, … Modulattion W. Noah Eckman, Anahita Nejatfard, … Eric A. Modulating modullation immune system is a Immnue treatment strategy of modlation medicine.

Of modulatiom top ten drugs by sales inImmune system modulation acted on the immune system, including, notably, the messenger Immune system modulation mRNA -based vaccines for COVID ref. Beyond its established role in vaccine development, immunomodulation has therapeutic potential for various conditions including autoimmunity and cancer, modultaion well as inflammatory, fibrotic and modulatiln diseases.

However, immunomodulation Immune system modulation a two-edged sword, as is most modulaton demonstrated in the field of cancer modilation, where despite inducing systemm anti-tumour immunity, systemic administration of many Immunw drugs has resulted in immune-related adverse events distal to tumour sites 2.

Immine, delivering precise dosages of eystem drugs with movulation control to specific cells and tissues, while avoiding unwanted off-target stimulation, is essential Immube ensure a safe and effective immune response.

Targeting of immune Im,une can be Immun using traditional protein-engineering strategies, employing monoclonal antibodies, engineered binding proteins sydtem recombinant native mosulation for immune cell surface receptors. These approaches are at eystem stages of modylation development, with mono- and multi-specific antibodies being the most advanced 3systemm567.

These organs serve as command centres of mdoulation immunity where activation of Immmune B and T lymphocytes occurs Fig. Lymph nodes interface with peripheral tissues through lymphatic modulatin, Immune system modulation drain modualtion fluid from all tissues and provide a conduit for immune cell trafficking.

Drugs and vaccines can be Immune system modulation to lymph nodes through lymphatic uptake following parenteral injection. These approximate size ranges depend on Kiwi fruit ripening process tissue site of injection which can vary in ECM and lymphatic composition and factors such as injection volume Liver Health Awareness Campaign rate IImmune can cause Immune system modulation expansion of the flaps mediating entry into lymphatic vesselsespecially in small-animal models, where tissue volume relative to injection volume is much smaller.

Furthermore, particle shape, charge and surface chemistry can also play a part by promoting or hindering convection through the tissue and lymphatic entry Notably, capture of particles at the downstream dLN is a less studied but equally important prerequisite for lymph node modulation, as evidenced by data showing that proteins 12 and small hydrophilic nanoparticles 13 can pass through the entire lymphatic chain, reach the thoracic duct and enter the systemic circulation following a parenteral injection.

In this regard, using adjuvants that promote compound entry into lymph nodes 14or designing carriers that stimulate recognition by macrophages lining the subcapsular and medullary sinuses, can prove useful aPassive targeting of lymphatics through particle size.

bTargeting migratory leukocytes to traffic vaccines and therapeutics to draining lymph nodes. Shown are examples of injectable or implantable biomaterials that attract monocytes or dendritic cells from the local tissue and peripheral blood. The cells are then stimulated by the implanted material, triggering activation and differentiation into migratory antigen-presenting cells that carry antigens or other compounds to the draining lymph nodes.

ECM, extracellular matrix. Protein nanoparticles with surface-arrayed antigens and a size optimized for efficient lymphatic uptake enhance the immunogenicity of vaccines 16171819 Protein nanoparticle vaccines are currently in clinical trials for human immunodeficiency virus HIVSARS-CoV-2 and influenza, and have been shown to be safe and elicit potent neutralizing antibody responses in humans 2122 Table 1.

Another strategy to promote lymphatic uptake is to exploit albumin and lipoproteins that naturally traffic from blood to lymph. Amphiphilic conjugates — consisting of peptides, proteins or small molecules linked to an albumin-binding lipid tail through a hydrophilic poly ethylene glycol PEG spacer called amph-vaccines — bind to endogenous albumin in the tissue following parenteral injection, improving lymph node targeting 262728 For example, conjugation of an albumin-binding lipid tail to a CpG oligonucleotide adjuvant resulted in a fold increase in lymph node exposure following subcutaneous immunization in mice, compared with unmodified CpG This approach is currently being tested in the clinic for lymph node targeting of a cancer vaccine NCT; Table 1 Lymph node-targeting nanoparticles are also being used to deliver latency-reverting drugs in HIV cure strategies 31 and to induce immunological tolerance 323334 Nanoparticles composed of self-assembled proteins, synthetic bioresorbable polymers or lipid assemblies have different in vivo lifetimes and stabilities that can affect their functionality.

For example, proteolysis of protein nanoparticle vaccines could lead to particle disassembly and loss of antigen multimerization. However, such effects have received limited attention to date. Complementary to the strategy of direct lymphatic targeting, this approach leverages the natural process by which immune cells, including dendritic cells DCsmonocytes and neutrophils, internalize antigens in peripheral tissues and transport them to lymph nodes as part of their constitutive immune surveillance Fig.

For example, subcutaneously implanted porous polymer scaffolds releasing the cytokine granulocyte—macrophage colony-stimulating factor GM-CSF attract and differentiate monocytes into the DC lineage.

Molecular adjuvants and tumour antigens carried by these scaffolds are taken up by the recruited cells and transported to dLNs 3637 Fig. Data from this trial are not yet published, but should provide important insights into the safety of generating a strong localized inflammatory reaction at the implant site, an approach that could be extended to applications beyond cancer.

To avoid implantation, injectable polymeric hydrogels 38 or suspensions of biodegradable silica particles 39 have been employed, resulting in both cellular and humoral immune responses against cancer or microbial antigens DC-attracting biomaterials are also being developed to programme tolerance rather than immunity.

Dual-sized poly lactide- co -glycolide PLGA particles consisting of small 0. This example highlights the potential of DC-attracting approaches not only to modulate immunity, but also to programme tolerance.

Lymph nodes are highly organized organs with defined compartments enriched in different immune cell subsets. Afferent lymph enters the subcapsular sinus SCS of the lymph node, a fluid space between the lymph node capsule and the lymph node parenchyma, lined by lymphatic endothelial cells and macrophages Fig.

Within the parenchyma, many of the key cell populations regulating adaptive immunity have specific niches; B cells and follicular dendritic cells FDCs reside in follicles arrayed around the exterior of the node, whereas T cells are localized deeper in the lymph node paracortex 4546 Fig.

This physical segregation has an important role in orchestrating sequential steps in the immune response, so targeting distinct niches in the lymph node could offer valuable therapeutic opportunities.

Under physiological conditions, substances in the lymph can pass into the parenchyma through narrow collagen conduits, or be captured and transferred into the lymph node interior by SCS macrophages 474849 Fig.

Vaccine adjuvants such as oil-in-water nanoemulsions and saponin nanoparticles have been used to boost entry of compounds into lymph nodes by inducing rapid death of SCS macrophages 145253 Fig.

Similarly, liposomal formulations of clodronate, which is widely used to deplete SCS macrophages, improve antigen entry into lymph nodes In a two-stage delivery strategy, CpG oligonucleotides were coupled to approximately nm poly propylene sulfide PPS nanoparticles through cleavable oxanorbornadiene linkers and then injected intradermally in a murine model of lymphoma By tuning the chemistry of the oxanorbornadiene linker, the CpG adjuvant payload remained bound to the nanoparticles during trafficking to the dLN, and were later released deep into the lymph node parenchyma Fig.

aPromoting therapeutic entry into lymph nodes through depletion of subcapsular sinus SCS macrophages. Vaccine adjuvants red induce rapid death of SCS macrophages, leading to enhanced entry of antigens and other compounds gold into lymph nodes.

They chemically release small-molecule payloads red that rapidly permeate throughout the node. cSoluble polymers and polymer nanoparticles conjugated with ligands for receptors expressed by specific target cell types such as dendritic cells are taken up by antigen-presenting cells in lymph nodes and co-deliver vaccine antigens or dendritic cell-activating compounds for example, TLR agonists.

d1 Nanoparticles activate complement, 2 are captured by SCS macrophages 3 and transferred to non-antigen-specific B cells through complement receptors. e1 Ligands for chimeric antigen receptor CAR T cells linked to albumin-binding poly ethylene glycol PEG -lipid moieties traffic from an injection site and bind to endogenous albumin.

These compounds are then transferred to lymph nodes 2 where they are inserted into the plasma membrane of macrophages and dendritic cells. Subsequent encounter of CAR T cells with the ligand displayed on the surface of dendritic cells 3 will lead to CAR T cell tandem stimulation by natural costimulatory receptors and cytokine signals provided by the ligand-decorated dendritic cells.

To facilitate intra-nodal delivery, specific cell populations can be targeted within the lymph node parenchyma, in particular DCs and macrophages. For example, oral or systemic administration of rapamycin promotes tolerance by acting on DCs and myeloid cells for example, in organ transplantsthough with considerable systemic side effects To drive antigen-specific tolerance, lymph node DCs were targeted using liposomes co-delivering a tolerance-driving aryl hydrocarbon receptor agonist drug together with a multiple sclerosis-related peptide in a murine multiple sclerosis model DC targeting has also been achieved by targeting specific receptors expressed by these cells.

Following intradermal vaccination, polymer chains functionalized with antigens, TLR7 agonists and mannose moieties to target mannose receptor-positive DCs improved uptake of antigens in lymph nodes Fig.

These studies highlight the potential of co-delivering antigens and adjuvant compounds to the same cell through physical conjugation or encapsulation within the polymer carrier, a widely adopted strategy 5961 Moreover, the physical chemistry of antigen and adjuvant compounds, together with selective design of nanoparticle carriers to enable release into DCs upon arrival in the lymph nodes, are important to consider to ensure optimal T cell priming and functional polarization 6263 For example, autoimmune-related peptide antigens coupled to nm quantum dots trafficked from subcutaneous injection sites to dLNs, where they accumulated in macrophage receptor with collagenous structure MARCO -positive macrophages Therefore, targeting these lymph node APC populations seems promising for promoting both immunity and tolerance.

Of note, in this work, quantum dots were used owing to their bright fluorescent properties, but are known to release toxic metals over time In general, an important question to address with any polymer-based or nanoparticle-based DC-targeting strategy is whether the material is effectively captured in the dLN chain following injection, or whether it passes through the thoracic duct and enters the systemic circulation 13raising potential toxicity concerns, in particular for potent immunostimulants.

B cell follicles are another important niche regulating humoral immune responses. Nanoparticles engineered to activate the complement system can target antigens or therapeutics to B cell follicles.

For example, nanoparticles bearing a high density of mannose-containing glycans are recognized by the innate immune protein mannose-binding lectin, which triggers complement deposition on the particles.

Upon arrival to the lymph nodes, SCS macrophages transfer complement-decorated particles to migratory B cells in the lymph node parenchyma, which in turn pass the particle to FDCs 5367 Fig. For vaccines, this strategy is glycan density dependent, amplifies the germinal centre and serum antibody responses and can be engineered into synthetic particles to promote follicle localization 67 In principle, particles triggering complement activation through natural immunoglobulin M IgM or the alternative pathway should also be capable of such FDC localization.

An important parameter to consider when designing carriers targeting B cells is that rigid particles carrying multivalent copies of an antigen are more effective than flexible polymers in triggering B cell activation

Credit: iStock. On This Page What are the types of immune system modulators? Which types of cancer are treated with immune system modulators? What are the side effects of immune system modulators? What are the types of immune system modulators? Types of immune system modulators include cytokines, BCG, and immunomodulatory drugs. Cytokines that are sometimes used to treat cancer: Interferons INFs. Researchers have found that one type of interferon, called INF-alfa, can enhance your immune response to cancer cells by causing certain white blood cells, such as natural killer cells and dendritic cells, to become active. INF-alfa may also slow the growth of cancer cells or promote their death. Interleukins ILs. There are more than a dozen interleukins, including IL-2, which is also called T-cell growth factor. IL-2 boosts the number of white blood cells in the body, including killer T cells and natural killer cells. Increasing these cells can cause an immune response against cancer. IL-2 also helps B cells another type of white blood cell produce certain substances that can target cancer cells. They promote the growth of blood cells that are damaged by chemotherapy: Erythropoietin , which increases the production of red blood cells. IL , which increases the production of platelets. Granulocyte-macrophage colony-stimulating factor GM-CSF and granulocyte colony-stimulating factor G-CSF , which both increase the number of white blood cells. Boosting white blood cells reduces the risk of infections. G-CSF and GM-CSF can also enhance the immune system response against cancer by increasing the number of cancer-fighting T cells. They include thalidomide Thalomid® lenalidomide Revlimid® p omalidomide Pomalyst® imiquimod Aldara®, Zyclara® Thalidomide, lenaliodomide, and pomalidomide cause cells to release IL
