The pathogenesis of<unk>  can be assessed based on the threshold of CD3+ or CD45+ cells surrounding or infiltrating the islets of Langerhans, however, this can only be studied with a pancreatic tissue sample. CD3+ and CD45+ (cluster of differentiation 3 & 45 positive cells) are lymphocytes. Studying non-obese diabetic mice has revealed a correlation between<unk>  progression and quantity of insulin autoantibodies production in the blood circulation, as well as a link between certain combinations of present autoantibodies and risk for developing type 1 diabetes and<unk> .<unk> , which is present in roughly 19% of type 1 diabetes patients, most prominently occurs in the first year after diagnosis in patients aged 0 to 14 years with a prevalence of 68% (32/47 patients studied).<unk>  prevalence is 4% in young patients with chronic type 1 diabetes (patients who have had the disease for over a year). Only 29% of older patients aged 15 to 39 have shown<unk>  lesion within a year after diagnosis. The exact reason for this disparity between age groups is unknown, however it is theorised that adults may have a different or less severe form of type 1 diabetes that progresses slower. There are 2 different sub-classifications of<unk> , peri-insulitis and intra-insulitis, that differ based on the location of immune cell infiltration. In peri-insulitis, cell infiltration occurs in the periphery of the islets, whereas in intra-insulitis has cell infiltration in the parenchyma, the functional tissue, of the islet. Often, in peri-insulitis, cell infiltration in concentration at 1 pole of the islet.none
