Host resistance and the immune system
Clin Geriatr Med.
1992 Nov.
Abstract
Elderly persons are more susceptible and vulnerable to many infections compared with young adults. This phenomenon can be attributed to a decline in host defense mechanisms, particularly altered immune function. The effects of aging on T- and B-lymphocyte function; antigen-presenting cells, natural killer cells, and granulocytes; and organ-specific host resistance are discussed in this article.
