title: Immune alterations in three mouse strains following 2-deoxy-D-glucose administration.
abstract: Using 2-deoxy-D-glucose (2-DG)-induced stress, our laboratory has developed studies to define stress effects on immune responses. Here, we report effects of increasing doses of 2-DG on the immune response of BALB/c, C57BL/6 and BDF(1) mice 2 h after three injections of 0 to 2000 mg/kg of 2-DG. Female 4- to 5-week-old mice were euthanized and blood and spleens were collected. A suspension of partially purified mature T splenocytes was obtained by negative selection using J11.d2 antibodies. Glucose and corticosterone levels were measured in the plasma of each mouse. Splenocyte and mature T splenocyte suspensions were tested in in vitro proliferation assays with or without concanavalin A. Splenocytes were analyzed for the following cell-surface markers: CD3, TCR alpha/beta, CD4, CD8 and major histocompatibility complex (MHC) Class II. Significant increases in blood glucose levels were observed in C57BL/6 and BALB/c strains with the highest 2-DG dose (p<0.05). Corticosterone levels were higher in BDF(1) mice and C57BL/6 mice following the administration of 1000 and 2000 mg/kg of 2-DG, respectively (p<0.01). In vitro proliferation of mature T splenocytes in the presence of concanavalin A was decreased in BDF(1) (p<0.05) but not in BALB/c and C57BL/6 mice. In addition, in BDF(1) mice the decrease was highly correlated with an increase of CD3+ and TCR alpha/beta+ cells in the spleen. These results demonstrated high variability in the response of different mouse strains to 2-DG-induced stress.
