α/β-hydrolase domain-containing protein 11 (ABHD11) is a mitochondrial hydrolase that maintains the catalytic function of α-ketoglutarate dehydrogenase (α-KGDH), and its expression in CD4+ T cells has been linked to remission status in rheumatoid arthritis (RA). Here, OGDH is linked to rheumatoid arthritis.
