“They sequenced the bacterial populations in the fecal samples before and after transplantation. Then they assessed the effects of the transplants on inflammatory hallmarks of aging (specifically, protein levels, immune function, and behavior).”

“Following infection with the SARS-CoV-2 infection, the adaptive immune system produces neutralizing antibodies that attack the virus and prevent further illness in those who recover. Vaccination provides another means of developing long-lasting immunity.”

“During infection with a virus, the innate immune system immediately produces inflammation to fight the infection. Within days or weeks, the adaptive immune system produces antibodies that are specific to the virus.”

“Psychosocial stress, such as that experienced with divorce, discrimination, trauma, or the death of a child, can have profound effects on the human body. For example, evidence indicates that stress alters the immune system, driving inflammatory processes and impairing antiviral responses.”

“There are several proposed mechanisms including immune system modulation (ie. inflammation) and changes in brain neurotransmitters via vagal nerve stimulation. More studies still need to confirm the efficacy of probiotics for the treatment of anxiety but results look promising.”

“Critical elements of the body's immune system are T-cells, a class of lymphocytes that promote an appropriate immune response and actively engage in the destruction of pathogens. Findings from two new studies suggest that people who are infected with SARS-CoV-2, the virus that causes COVID-19, have T-cells that target the virus.”

“Microglia are the brain's resident immune cells and their persistent activation can sustain inflammatory signaling that interferes with cognitive function. That finding supports an anti-inflammatory mechanism but remains preclinical.”

“However, mTOR activation in peripheral tissues, such as the vascular system, has been linked to atherosclerosis and cancer. Exercise resolves this issue by directing leucine toward muscle tissue, ensuring mTOR activation occurs where it's beneficial.”

“Previous work on other coronaviruses demonstrates that vitamin D can counteract a cytokine storm by strengthening the innate immune response and inhibiting the adaptive immune system from over-responding to a viral infection.”

“SARS-CoV-2, the virus that causes COVID-19, stimulates the innate immune system, causing systemic inflammation that damages the lungs. Evidence suggests that those with the most severe cases of COVID are made sicker not by increased viral replication, but by unregulated inflammation.”
