Type 1 diabetes: B cell-derived natural antibodies suppress autoimmune pathogenesis

Researchers found that vaccination of neonatal mice with group A Streptococcus promotes clonal expansion of innate-like B cells producing antibody against N-acetyl-D-glucosamine (GlcNAc), reducing Type 1 diabetes risk. These GlcNAc-specific B-1 B cells aid in producing tolerance, facilitating efficient clearance of apoptotic beta cells...

Young age at first menstrual cycle linked to heightened diabetes risk in mid-life

Research found a heightened risk of type 2 diabetes and stroke in women who started menstruating before age 13. Earlier age at first menstrual cycle was associated with higher diabetes risk after adjusting for influential factors, while very early age (10 or younger) linked to more than doubling stroke risk among those with diabetes.
