Peroxisomes are ubiquitous organelles which participate in a variety of essential biochemical pathways. An intimate interrelationship between peroxisomes and mitochondria is emerging in mammals, where both organelles cooperate in fatty acid β-oxidation and cellular lipid homeostasis. As mitochondrial fatty acid

Adenosylcobalamin-dependent isomerases catalyze carbon skeleton rearrangements using radical chemistry. We have recently demonstrated that an isobutyryl-CoA mutase variant, IcmF, a member of this enzyme family that catalyzes the interconversion of isobutyryl-CoA and n-butyryl-CoA also catalyzes the interconversion between isovaleryl-CoA and

Proteinase-activated receptor-2 (PAR2) is involved in dermatophyte-induced scratching and leukotriene B4 (LTB4) release from keratinocytes. We investigated whether PAR2-mediated LTB4 production is involved in dermatophyte-induced scratching. Dermatophyte extract was injected intradermally and scratching was observed in mice. LTB4 was determined
