As we age, our immune system function
deteriorates, leaving us increasingly susceptible to health threats such as
cancer, autoimmunity, infections, and chronic inflammation. This process is
called immune senescence.
Scientists are
studying various methods for countering immune senescence, including young
stem-cell mobilized plasma transfusions. Research suggests old blood may
contain pro-aging factors whose concentrations are diluted by young-blood
transfusions, potentially causing rejuvenating effects.
In addition,
several natural interventions, including cistanche, reishi, and zinc may
slow or potentially reverse the course of immune senescence.
How Aging Accelerates Immune Decline
Decreased numbers of naïve T cells, or cells that can easily be
activated to recognize and respond to diseases like the flu and cancer.
Increased numbers of senescent memory T cells that have lost
their ability to divide and function properly and instead release
pro-inflammatory molecules.
Decreased natural killer (NK) cell activity, which is linked to increased
illness and death from infections, atherosclerosis, and diminished response to
the flu vaccine.
Cytomegalovirus infection may be associated with immune senescence,
cardiovascular disease, frailty, and mortality.
Some of the above compounds read like effective anti-aging substances. Check out what NCBI says about Herba Cistanche,
Herba Cistanche extracts are pharmacologically active, with a range of functions that include improving chronic renal disease and senile constipation, increasing learning/memorizing ability, treating Alzheimer's disease (AD), and improving immunity.
