A newly recognized set of T helper cells seems to guard against aging by eliminating harmful senescent cells. Their presence in supercentenarians suggests they may be a key to maintaining a healthier, ...

As people age, their immune system function declines. T cell populations become smaller and can't react to pathogens as quickly, making people more susceptible to a variety of infections. To try to ...

It boosted the number of well-functioning CD8+ T cells (also known as cytotoxic T lymphocytes, or CTLs), which are important for fighting pathogens. These cells were found to have more peroxisome ...

During vaccination, the immune system is purposefully exposed to weakened, inactivated, or a component of pathogens so that the body can recognize their molecular structures in the future and mount a ...

Researchers have discovered a way to help aging intestines heal themselves using CAR T-cell therapy. By targeting senescent cells that build up over time, the treatment boosted gut regeneration, ...

ROCHESTER, Minn. — Mayo Clinic researchers have discovered a key reason some cancer patients relapse after receiving chimeric antigen receptor T-cell therapy, or CAR-T cell therapy. Over time, the ...

As people age, their immune systems deteriorate. This makes them more susceptible to infections and can mean that vaccines are less effective. New research carried out by Dr. Loren Kell at NDORMS ...
