Collagen-and collagen peptide-induced chemotaxis of human blood monocytes

The ability of collagen and collagen-derived peptides to act as chemotactic stimuli was investigated by in vitro chemotaxis assays. Native human and chick skin collagen (type I) and alpha-chains obtained from purified chick skin collagen were each chemotactic for human peripheral blood monocytes. In addition, smaller peptides obtained either by digesting native collagen with bacterial collagena...

Measles infection of human mononuclear cells. I. Acute infection of peripheral blood lymphocytes and monocytes

A study of the susceptibility of human peripheral blood mononuclear cells to measles virus infection and replication is reported. Resting lymphocytes obtained from adults showed very low levels of infection and virus replication while lymphocytes activated by plant mitogens or allogenic lymphocytes supported mononuclear cells obtained from the umbilical cord of healthy neonates were more suscep...

Differential processing of proenkephalin-A by human peripheral blood monocytes and T lymphocytes.

Human peripheral blood mononuclear cells are analyzed for preproenkephalin gene expression and peptide processing. Met-enkephalin immunoreactivity as detected with a specific antiserum is found in the cytoplasm of monocytes but not in T lymphocytes. Secretion of met-enkephalin was analyzed with an RIA that is specific for the met-enkephalin pentapeptide. Unfractionated PBMC spontaneously releas...

Chemotaxis of human neutrophils and monocytes induced by Cryptococcus neoformans.

Chemotaxis of human neutrophils and monocytes was stimulated by sera activated with greater than or equal to 1.25 x 10(6) Cryptococcus neoformans. Leukocytes from five renal transplant recipients had depressed chemotactic responses to C. neoformans-activated sera when compared with normal subjects (P less than 0.05). Concentrations of cryptococcal capsular polysaccharide less than 1 mg/ml faile...
