The plasma membranes of phagocytic leukocytes have receptors for the Fc portion of IgG (1-6) and for a cleavage product of the third component of complement, C3 (3, 4, 6-8). These receptors are distinct from one another (1-3) and serve different functions in promoting the interaction of phagocytic cells with immunologically coated particles and soluble material in the cells' environment (6-10)....
OBJECTIVE Macrophages are an important reservoir for the HIV and contribute to innate lung defense by their ability to phagocytose, digest, and process invading pathogens. We hypothesized that HIV-1 infection may lead to a defect in the phagocytic activity of alveolar macrophages. DESIGN In order to test this hypothesis, the phagocytic activity of alveolar macrophages from asymptomatic HIV-1 ...
There are three major classes of human Fcg receptors (FcgRI, FcgRII, and FcgRIII) and various isoforms of each class are capable of mediating phagocytosis. FcgRIIA is an unusual Fcg receptor in that it transmits a phagocytic signal in the absence of an additional receptor subunit. The cytoplasmic domain of FcgRIIA contains a conserved motif containing two copies of the sequence YXXL. The tyrosi...
