A mechanistic understanding of the effects of IL-1 on the beta-cell may clarify its role in modulating insulin release in vivo or yield insight into the pathogenesis of IDDM.

The potentiation of IL-1 effects on beta-cells by tumor necrosis factor alpha (TNF), another macrophage hormone controlled by a gene in the HLA region on chromosome 6, may account for the MHC association of IDDM.

In the experimental model of IDDM etiopathogenesis described, release of beta-cell antigen, processed and presented by macrophages to helper T-lymphocytes, initiates a self-perpetuating and self-limiting circuit of cytokine production of which IL-1 is beta-cell cytotoxic.

It has been postulated that one of the factors causing immune-mediated pancreatic beta-cell destruction in insulin-dependent diabetes mellitus (IDDM) is interleukin-1 (IL-1).

Significant increases in platelet and PBMC membrane eicosapentaenoic acid was found in omega-3-PUFA-treated individuals. omega-3-PUFA treatment significantly reduced the content of IL-1 beta in lysates of PBMC, but did not affect PBMC or Mo secretion of IL-1 beta, TNF-alpha or prostaglandin E2 (PGE2) or PBMC leukotriene B4 (LTB4) secretion in healthy subjects or in IDDM patients.

In the present study we have measured IL-1, IL-2, IL-4, IL-6, interferon-gamma (IFN-gamma) and tumour necrosis factor (TNF) (using both immunoassays and bioassays) in sera from 50 patients affected by IDDM at the time of clinical diagnosis and 51 age and sex matched controls.

In this study we tested whether the effects of daily human recombinant IL-1 beta injections on leukocyte subsets were associated with its modulation of IDDM onset in BB rats.

|
Prior to the onset of IDDM in DP BB rats, high dose IL-1 beta induced leukocytosis (P less than 0.05), neutrophilia (P less than 0.01), and monocytosis (P less than 0.001).

|
In 60-day-old diabetes-resistant (DR) BB rats, neurophilia was induced by both low (P less than 0.05) and high (P less than 0.001) dose IL-1 beta without the development of IDDM.

These data show for the first time that IL-1 and IL-6 secretion by an insulinoma cell line may occur after viral infection and suggest that cytokine release and increased expression of HLA molecules by beta cells may act to induce the immune response towards beta cells in IDDM.

We argue that IL-1 potentiated by other cytokines (tumor necrosis factor alpha, interferon gamma) is an important effector molecule involved in both early and late events in the immune-mediated process that leads to beta-cell destruction and IDDM.
|

We suggest that the selectivity of beta-cell destruction in IDDM may be conferred on several levels: (1) homing of beta-cell antigen specific T cells, (2) targeted delivery of cytokines by lymphocytic and monocytic cells beta-cells, (3) high molar excesses of IL-1ra over IL-1 needed to prevent IL-1 mediated beta-cell toxicity, (4) increased beta-cell sensitivity to free nitric oxide and oxygen radical formation induced by IL-1 and (5) inadequate oxidative stress response by beta-cells to cytokines.

Further studies are needed to establish the in vivo role of an imbalance between the amounts of IL-1 and IL-1ra produced relative to their action in the pathogenesis of IDDM.

|
It is concluded that the gradual increase in IL-1 beta and TNF alpha plasma levels may reflect an ongoing autoimmune inflammatory reaction at the onset of IDDM.

In the nonobese diabetic (NOD) mouse, a spontaneous model of IDDM, it was put forward that the disease is linked to a susceptibility locus, called idd5, which contains the IL-1 receptor (IL-1R) gene.

Since glutamic acid decarboxylase-65 (GAD-65) is a target autoantigen in IDDM, we investigated whether the cytokines IL-1 beta, TNF alpha IFN gamma altered islet cell expression of GAD-65 and whether the effect of cytokines on GAD-65 expression was similar to their effect on insulin secretion.
