The transglutaminase involvement in phytohaemagglutinin (PHA) stimulated lymphocyte transformation (measured as (3H)thymidine incorporation) was studied in lymphocytes from 20 patients with type 2 diabetes mellitus and 20 healthy controls by including in the system the specific transglutaminase pseudosubstrate monodansylthiacadaverine (MDTC). In the presence of MDTC, (3H)thymidine incorporation was significantly and concentration-dependently reduced in both groups but more pronouncedly in the diabetes patients. The MDTC concentration needed to give a 50% reduction of the PHA-stimulated (3H)thymidine incorporation was significantly lower in lymphocytes from diabetic patients than in those from controls (p less than 0.02). The data suggest impaired lymphocyte transglutaminase function in type 2 diabetes mellitus.

UI MeSH Term Description Entries
D008213 Lymphocyte Activation Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D011503 Transglutaminases Transglutaminases catalyze cross-linking of proteins at a GLUTAMINE in one chain with LYSINE in another chain. They include keratinocyte transglutaminase (TGM1 or TGK), tissue transglutaminase (TGM2 or TGC), plasma transglutaminase involved with coagulation (FACTOR XIII and FACTOR XIIIa), hair follicle transglutaminase, and prostate transglutaminase. Although structures differ, they share an active site (YGQCW) and strict CALCIUM dependence.
