Sensitization to insulin induced by beta,beta'-methyl-substituted hexadecanedioic acid (MEDICA 16) in obese Zucker rats in vivo.

abstract：:Antibodies to islet cell proteins detected as 37,000 and 40,000 M(r), tryptic fragments (37- and 40-kDa antigens) are strongly associated with progression to IDDM. The 40-kDa antigen has recently been identified as the tyrosine phosphatase-like protein IA-2 (ICA512) whereas the 37-kDa antigen has been suggested to be ...
