But the role of sex in immune system aging is not well understood. An NIA-supported study took a closer look at how the timing and degree of aging-related changes in the immune system varies among men and women and identified how particular immunity characteristics diverge as we grow older. Building upon their previous studies of how aging affects immunity, a team led by scientists at The Jackson Laboratory, Farmington, Connecticut, looked deeper into the underlying molecular and genetic mechanisms behind sex differences in immunity at different stages of life. Their findings were published in the journal Nature Communications. The team surveyed the blood-based immune cells of healthy adult volunteers 81 men and 91 women between the ages of 22 and 93, with an eye toward balancing gender, body mass index, frailty scores, and other health attributes to form three age-based groups: young less than 41 years old , middle-aged between 41 and 64 , and older over They also performed genetic analyses to track how the expression of different genes affected immune function over time.

Maher: The Key To Beating COVID Is Your Immune System, "You Can't Keep All The Pathogens Out"
Unprecedented efforts and diverted resources mean we are fast learning about human defences against this new threat. A s the daughter of an air force officer and a nurse, I am fascinated by defence systems. There is none more impressive than the human immune system, equipped as it is with a rich arsenal to defend against different types of pathogen. Viruses have evolved to trick, bypass and evade these defences.
Objective: Sexual arousal and orgasm induce an increase in sympathetic activity as well as in catecholamine and prolactin plasma concentrations. However, the effects of sexual arousal and orgasm on immune functions in man are unknown. Thus, this study investigated the effects of masturbation-induced orgasm on lymphocyte circulation and cytokine production in healthy young males.
