[Chemotactic function of skin fibroblasts in patients with amyloidosis].
Chemotaxis of cultivated fibroblasts, obtained from patients with amyloidosis, chronic glomerulonephritis and healthy volunteers, was investigated. Fibroblast migration toward donor serum and serum from patients with amyloidosis was measured using Boyden chamber's technique. As "zero" chemoattractant Hank's solution was used. It was shown, that chemotactic index (CI) was independent from cell density. Significant CI depression of fibroblasts from patients with amyloidosis toward donor serum in contrast to fibroblasts from patients with chronic glomerulonephritis and healthy volunteers was shown. The depression of chemotactic function was the same with fibroblasts from patients with different variants of amyloidosis and different stages of amyloid nephropathy and was stable in several cell generations. The results obtained suggest the existence of primary hereditary variant (variants) of chemotactic function, which may lead to the development of amyloidosis in certain conditions.
