o Leukocytes lack the complement receptor CR3 due to a defect in CD11 or CD18 peptides and consequently they cannot respond to C3b opsonin. o Alternatively there may a defect in integrin molecules, LFA-1 or mac-1 arising from defective CD11a or CD11b peptides, respectively. o These molecules are involved in diapedesis and

times of stress, corticosteroids, complement fragments, and catecholamines accelerate the release of mature neutrophils, as well as meta-myelocytes and band cells, into the circulation. Chemotactic substances such as C5a, inter-leukin 8 (IL-8), monocyte chemotactic factor, leukotrienes, and bacterial peptides induce the

The summary of the results from these studies is presented in Table 2 In monocytes, all the recep-tors were upregulated in bacterial and viral infections.

They are mostly of IgG class, although IgM may also be involved. The reaction takes hours to days (3-10 hours) to develop. The antigen may be exogenous (chronic bacterial, viral or
