Immune system resilience -

Their studies have shown that high expression of the survival-associated genes and lower expression of mortality-associated genes indicate optimal immune resilience, correlating with a longer lifespan.

The opposite pattern indicates poor resilience and a greater risk of premature death. When both sets of genes are either low or high at the same time, immune resilience and mortality risks are more moderate.

In the newly reported study initiated in , Ahuja and his colleagues set out to assess immune resilience in a collection of about 48, people, with or without various acute, repetitive, or chronic challenges to their immune systems.

In an earlier study, the researchers showed that this novel way to measure immune status and resilience predicted hospitalization and mortality during acute COVID across a wide age spectrum [2]. The investigators have analyzed stored blood samples and publicly available data representing people, many of whom were healthy volunteers, who had enrolled in different studies conducted in Africa, Europe, and North America.

Volunteers ranged in age from 9 to years. They also evaluated participants in the Framingham Heart Study, a long-term effort to identify common factors and characteristics that contribute to cardiovascular disease.

To examine people with a wide range of health challenges and associated stresses on their immune systems, the team also included participants who had influenza or COVID, and people living with HIV.

The short answer is that immune resilience, longevity, and better health outcomes tracked together well. Those with metrics indicating optimal immune resilience generally had better health outcomes and lived longer than those who had lower scores on the immunity grading scale.

Indeed, those with optimal immune resilience were more likely to:. The study also revealed other interesting findings.

Some people also maintain higher levels of immune resilience despite the presence of inflammatory stress to their immune systems such as during HIV infection or acute COVID People of all ages can show high or low immune resilience. The study also found that higher immune resilience is more common in females than it is in males.

The findings suggest that there is a lot more to learn about why people differ in their ability to preserve optimal immune resilience. With further research, it may be possible to develop treatments or other methods to encourage or restore immune resilience as a way of improving general health, according to the study team.

It could also help to identify those individuals who may be at a higher risk of poor outcomes when they do get sick and may need more aggressive treatment.

Researchers may also consider immune resilience when designing vaccine clinical trials. A more thorough understanding of immune resilience and discovery of ways to improve it may help to address important health disparities linked to differences in race, ethnicity, geography, and other factors.

This research was supported in part by NIA grants AG and AG and the Intramural Research Program at NIA. Immune resilience despite inflammatory stress promotes longevity and favorable health outcomes including resistance to infection. Nature Communications. A good development of the immune system in early life is associated with an improved health status later in life and vice versa.

asthma, rhinitis later on life. WAO White Book on Allergy. Published on , Wisconsin contributing to the epidemic in non-communicable diseases NCDs. As you grow older, the functioning of your immune system declines.

Overall, the immune system responds slower and less effectively, thereby becoming less efficient in its defences and increasing the risk of getting ill. Besides ageing, the immune system can also be impacted by malnutrition, disease or genetic disorders.

When the immune system functions less effectively, this leads to a higher risk of a variety of health issues, such as: slower recovery, infections, chronic inflammation, cancer, immobility or autoimmune disorders.

Many of our immune cells live in the gastrointestinal tract 2 West CE, et al. J Allergy Clin Immunol. Published on Jan; 1 along with the trillion gut bacteria that make up the gut microbiota. As the gut is a major entrance for pathogens, toxins and allergens, one of the main roles of the immune system in the gastrointestinal tract is to distinguish between harmless antigens, such as food, and health hazards.

The development and preservation of a healthy immune system coincides with the establishment and maintenance of a healthy gut microbiota, and is directly linked to nutrition. R, Orel ed ;. Ljubljana Institute for Probiotics and Functional Foods. Published on , 4 Azad MB, et al. Clin Exp Allergy.

Published on ;45 3 An imbalance of gut microbiota is associated with inappropriate immune responses like allergic diseases, chronic inflammation and the development of NCDs.

Published on ; 2 e2 Conversely, a healthy gut microbiota is associated with improved health later in life, fewer NCDs, including a reduced risk of allergies and a lower persistence of allergic diseases. Published on , Wisconsin.

A meta-analysis of 35 Plant-based compounds found that compared Fat intake and cholesterol higher socioeconomic status SES Immuune, low SES exposure in childhood and adolescence increased levels of inflammation in adulthood measured by C-reactive protein CRPIL-6, and fibrinogen. Adequate and uninterrupted access to healthy and varied foods is essential for positive health outcomes. Dietary patterns that include anti-inflammatory foods such as fruits and vegetables supply nutrients and natural antioxidants that may contribute to a more robust immune system through reducing inflammation.

Some people remain healthier throughout life than others but the underlying reasons are poorly understood. Profiles of IR metrics in ~48, individuals collectively indicate that some persons resist degradation of IR both during aging and when challenged with varied inflammatory stressors. With this resistance, preservation of optimal IR tracked i a lower risk of HIV acquisition, AIDS development, symptomatic influenza infection, and recurrent skin cancer; ii survival during COVID and sepsis; and iii longevity.
