This month's Clinical & Experimental Immunology is a special issue highlighting the current state of play
in immunosenescence research.
SENS Foundation is funding ongoing work in the lab of Dr. Janko Nikolich - Zugich to investigate the effects of clearance of anergic, «senescent» cytotoxic CD8 + T - cells
on immunosenescence, (22) and is interested in the targeting of other such cells.
IRP and low - grade inflammation predicted 57 % of observed deaths and 97 % of survival over 2 years, and was not significantly affected by individuals» health status, suggesting that the physiological ageing processes of T -
cell immunosenescence and low - grade inflammation are of primary importance in late life survival.
Finally, that the onset of Alzheimer's disease coincides
with immunosenescence, indicates that the immune system is constantly disposing of toxic oligomers while leaving plaque untouched, until due to its decline with age, the immune system is unable to remove those oligomers and the disease appears.
When asked how the recent findings relate to the other research in which his lab is engaged, Dr. Apte explained, «My laboratory has a strong interest in understanding the programmatic changes that occur with aging and lead to immunosenescence [age - related deterioration of the immune system] and neurodegeneration.
Replacing the chemotherapy with a safe, side - effect - free treatment would mean that the established programs for immune system restoration could immediately expand to become a useful, effective treatment
for immunosenescence, the age - related failure of the immune system.
Dr. Jabs and colleagues note that further exploration of these findings may provide the opportunity to better understand the roles
of immunosenescence and systemic inflammation in the development of AMD, which in turn could lead new treatments.
This process,
called immunosenescence, is intimately related to mitochondrial function and energy balance, 33 both of which depend on NAD + activity.
Rather they point out that antiretroviral - treated, immune - restored, HIV - infected patients do not have normal immune systems; instead and on average they have immunologic changes similar to those seen in patients who are not infected who are older than 70 years of age, a phenomenon termed «
immunosenescence.»
The decline of the immune system with age (
immunosenescence) is reflected in the increased susceptibility to infectious diseases, poorer response to vaccination, increased prevalence of cancer, accelerated aging (frailty), autoimmune and other chronic diseases.
In this sense, then, we suggest that
immunosenescence is contagious.
The workshop will include research on stem cells and aging, implications of aging on immune function (
immunosenescence, immune reconstitution), thrombosis and aging, and correlates of frailty in hematology.
Conclusion: Adequate intracellular NAD + is vital for youthful cellular energy, a critically important factor in fending off
immunosenescence and maintaining defenses against infections and autoimmune disease.
