- AB Peripheral blood mononuclear cells from patients with
- non-insulin-dependent diabetes mellitus (NIDDM) show reduced
- proliferative response to phytohemagglutinin (PHA) and other mitogens.
- This study was undertaken to determine whether this reduced lymphocyte
- proliferation is mediated by a decreased production of cytokine or
- decreased expression of interleukin-2 receptor (IL-2R). Mononuclear
- cells from NIDDM patients (n = 34) and healthy controls (n = 22) were
- cultured in RPMI-1640 media containing PHA, concanavalin-A and phorbol
- myristate acetate. NIDDM patients showed reduced [3H]thymidine uptake
- (57% of controls, P < 0.01), reduced percentage of IL-2R-positive cells
- (61% of controls, P < 0.02) and increased level of tumor necrosis factor
- (TNF)-alpha (200% of controls, P < 0.05). The percentage of complement
- receptor (CR) 3-positive monocytes from NIDDM patients was also
- decreased (72% of controls, P < 0.05). However, the production of IL-1
- beta, IL-2 and interferon-gamma, the percentages of pan T cells (CD3), T
- helper cells (CD4), T suppressor cells (CD8), the ratio of CD4/CD8 and
- the expression of CR1 and Fc receptors for immunoglobulin G (Fc gamma
- RII and Fc gamma RIII) were not significantly different between NIDDM
- patients and healthy subjects. Human recombinant IL-2 was unable to
- restore the [3H]thymidine uptake by PHA-stimulated mononuclear cells
- from NIDDM patients. Elevation of glucose concentration up to 27.8
- mmol/l in the culture medium did not suppress the [3H]thymidine uptake
- and IL-2R expression by activated lymphocytes from healthy subjects. The
- decreased expression of IL-2R on activated lymphocytes might be
- responsible for the insufficient lymphocyte proliferation in NIDDM
- patients. These findings suggest that decreased expression of CR3 on
- monocytes, decreased lymphocyte proliferation and decreased IL-2R
- expression despite a higher production of TNF-alpha may explain the
- impaired cell-mediated immunity seen in NIDDM patients.
