Immunological effects of D-penicillamine during experimental induced inflammation in rats

Abstract

Administration of D-penicillamine (50 mg/kg/day orally) to rats with adjuvant arthritis for up to 42 days significantly modified the incorporation of 3H-thymidine (3H-TdR) in concanavalin A (Con A)-stimulated lymph node cells. Treatment with D-penicillamine abolished the ability of macrophages from arthritic rats to inhibit lymphocyte responsiveness to Con A and lipopolysaccharide (LPS) 14 days after the induction of the disease. Increased T-cell responsiveness to Con A was found from day 14 to 35 in cultures of unseparated and adherent-cell-depleted lymph node cells from D-penicillamine-treated arthritic rats. B-cell responsiveness to LPS was not affected. Experiments with bovine serum albumin gradient-separated lymph node cells confirmed these findings and indicated that treatment with D-penicillamine may specifically enhance T-helper cell responsiveness to Con A. It is suggested that administration of D-penicillamine may interfere with macrophage function during the course of an immunologically induced chronic inflammation, leading to an increased response of T-helper cells. The theoretical implications of these findings are discussed.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
