Chediak-Higashi-syndrome cultured fibroblasts

چکیده
Chediak-Higashi-syndrome cultured skin fibroblasts were used to study the possible involvement of lysosomal enzymes and lysosomal dysfunction in this disorder. Our evidence indicated that Chediak-Higashi fibroblasts displayed a significant decrease in the specific activity of the acidic a-D-mannosidase (pH 4.2) compared with normal controls. Additional studies revealed a small, but significant, decrease in the rate of degradation of 1251-labelled fl-D-glucosidase that had been endocytosed into Chediak-Higashi cells.

Carbamycholine prevents giant granule-formation in cultured fibroblasts from beige (Chediak-Higashi) mice
Primary embryonic fibroblasts isolated from beige (Chediak-Higashi) mice develop pathognomonic giant granules in vitro. Inclusion in the culture medium of carbamylcholine (carbachol) or phorbol myristate acetate (PMA) results in the generation of morphologically normally granules. Chediak-Higashi fibroblasts are highly susceptible to shape changes induced by colchicine. This abnormal property i...
متن کاملDistribution pattern of lysosomal granules in fibroblasts of the Chediak-Higashi syndrome.
Cultured fibroblasts from a patient with the Chediak-Higashi syndrome, the mother of the patient, and a normal control were studied by light and electron microscopy. The distribution pattern of PAS-positive and acid phosphatase-containing granules in the cytoplasm differed significantly in the fibroblasts from the patient when compared with those from the mother and control. The granules in the...

متن کاملThe cytoskeleton in Chediak-Higashi syndrome fibroblasts.
The Chediak-Higashi syndrome (CHS) trait is expressed in cultured human skin fibroblasts as an abnormal perinuclear concentration of moderately enlarged lysosomes. The cytoskeleton of CHS fibroblasts appears intact. Microtubules are normal in number and morphology, as assessed by colchicine binding studies, antitubulin immunofluorescence, and electron microscopy. Deformability by shear force is...
متن کاملAbnormal bactericidal, metabolic, and lysosomal functions of Chediak-Higashi Syndrome leukocytes.
Phagocytic, antimicrobial, and metabolic functions were studied in leukocytes obtained from three patients with the Chediak-Higashi syndrome (CHS) and compared to normals, individuals, heterozygous for Chediak-Higashi syndrome, and two subjects with chronic granulomatous disease of childhood (CGD). Chediak-Higashi syndrome leukocytes showed normal ingestion of a variety of bacteria, Candida alb...
