1. Natural killer cell activity and monocyte cytotoxicity was evaluated in three subgroups of patients with primary hypogammaglobulinaemia (ten patients with late-onset, eight with X-linked and five with early-onset disease) and in two patients with secondary late-onset hypogammaglobulinaemia against the K-562 erythroleukaemia, the CaCo-2 colon carcinoma and the HGT-1 gastric carcinoma cell lin...
Natural Killer (NK) cells are the main lymphocyte population expressing P75 B chain of the IL-2 receptor (IL-2R). Consequently, incubation of peripheral blood lymphocytes with IL-2 induce selective activation of NK cells and results in NK activity and generation of Lymphokine activated killer (LAK) cells activity and proliferation. One of the early events during IL-2 activation of peripheral bl...
Background: Natural Killer cells express killer inhibitory receptors specific for HLA-class I molecules. These receptors could induce signals that determine NK cells ability to mediate cytotoxicity. Purified soluble form of HLA class I molecules (sHLA) could bind to NK cell receptors and down-regulate the NK killer function. Objective: To evaluate the influence of sHLA and two monoclonal an...
