The immune response during aging. 1979

A Członkowska, and J Korlak

Complex studies were carried out on humoral and cell mediated immunity among persons over 60 years of age and persons aged 18-40. Humoral immune responses were not profoundly disturbed in the group of older persons. The level of isoagglutinins was lower in older subjects, but the level of immunoglobulins and antibodies to widespread bacterial and virus antigens (S. typhi O, Kunin's CA, Parainfluenza types I, II and III) was the same in both groups. Cell mediated immunity was more greatly changed. Response to PPD in skin tests, lymphocyte stimulation tests, and the migration inhibition test was reduced in older subjects. Also, in this group, PHA in lymphocyte stimulation tests and the number of E- rosette forming cells was lower than among younger adults. However, responses to other antigens in skin tests, lymphocyte stimulation tests, migration inhibition tests (Candida albicans, SK-SD, Trichophyton) and responses to other stimulants of the lymphocyte stimulation tests (Con A, PWM) were well preserved in older subjects.

UI	MeSH Term	Description	Entries
D007111	Immunity, Cellular	Manifestations of the immune response which are mediated by antigen-sensitized T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role.

D007136	Immunoglobulins	Multi-subunit proteins which function in IMMUNITY. They are produced by B LYMPHOCYTES from the IMMUNOGLOBULIN GENES. They are comprised of two heavy (IMMUNOGLOBULIN HEAVY CHAINS) and two light chains (IMMUNOGLOBULIN LIGHT CHAINS) with additional ancillary polypeptide chains depending on their isoforms. The variety of isoforms include monomeric or polymeric forms, and transmembrane forms (B-CELL ANTIGEN RECEPTORS) or secreted forms (ANTIBODIES). They are divided by the amino acid sequence of their heavy chains into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M) and various subclasses.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D002464	Cell Migration Inhibition	Phenomenon of cell-mediated immunity measured by in vitro inhibition of the migration or phagocytosis of antigen-stimulated LEUKOCYTES or MACROPHAGES. Specific CELL MIGRATION ASSAYS have been developed to estimate levels of migration inhibitory factors, immune reactivity against tumor-associated antigens, and immunosuppressive effects of infectious microorganisms.
