Keywords: AIDS experimental check
Circulating lymphocytes significantly decreased, decrease in TH cells, TH / TS is greater than 1. 0; decline in T-cell function, the delayed type skin test negative, in vitro tests prove to non-specific ratio mitogen stimulation, T cell response decreases T the cell cytotoxicity decline, resulting in decreased interleukin-2 and a-interferon, is a cell dysfunction. Polyclonal hypergammaglobulinemia, to engage in the original stimulus should not students should antibody response and natural killer cell activity decreased.
Second, the virus and the antibody test:
Detect virus: Cell culture, virus isolation, detection of viral antigen, detecting toxic nucleic acids and detection of reverse transcriptase, the detection of HIV antibody screening tests immunological technique, enzyme linked immunosorbent assay (ELISA) and radioimmunoassay test, a strong specificity, there are the radioimmunoprecipitation test and protein blotting.
