Popis: | Levels of cAMP were decreased and cGMP increased in progressive systemic sclerosis (PSS) fibroblasts compared with normal fibroblasts. PSS cells took up unusually large quantities of Ca++. The epinephrine-induced increases in cAMP were diminished sixfold and epinephrine-induced Ca++ uptake was abnormal in PSS cells. Considerable heterogeneity was observed in rheumatoid arthritis fibroblasts. Membrane-bound abnormalities in (PSS) cells may be of importance in the defective control of collagen production in progressive systemic sclerosis. |
