Human lymphocyte cytotoxicity against target cells infected with influenza A viruses of both recent and old strains. 1979

F L Ruben, and L B Heilman

In vitro measurement of lymphocyte cytotoxicity (LC) reflects one aspect of human cell-mediated immunity against influenza. We studied peripheral blood LC against target cells infected with 1 of 3 strains of influenza A virus; these represent both recent and old strains. Positive LC responses were obtained in 94 % of subjects. Responses were significantly greater against the older strains, A/New Jersey/76 (Hsw1N1) and A/PR/8/34 (H0N1), than against A/England/42/72 (H3N2). LC reactivity occurred even in the absence of detectable HAI antibody titers. These results showed that positive LC responses to a variety of influenza A strains are common in normal adults and suggested that LC may be a more sensitive indicator of previous influenza exposure than conventionally measured HAI antibodies.

UI	MeSH Term	Description	Entries
D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009980	Influenza A virus	The type species of the genus ALPHAINFLUENZAVIRUS that causes influenza and other diseases in humans and animals. Antigenic variation occurs frequently between strains, allowing classification into subtypes and variants. Transmission is usually by aerosol (human and most non-aquatic hosts) or waterborne (ducks). Infected birds shed the virus in their saliva, nasal secretions, and feces.

D005455	Fluorescent Antibody Technique	Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.
