Abstract Resistin, that was originally discovered in 2001 is named for its capacity to resist insulin action shown mainly in mice. However, there is a controversial history regarding its role in the pathogenesis of insulin resistance and type 2 diabetes mellitus (T2DM) in humans as most of the research was based on association between resistin blood levels and T2DM or other pathologies and so far the pharmacological e!ect of recombinant resistin has not been tested in humans or even in primates. Resistin is a 12 kD cysteine-rich small protein acting as covalent dimer. Although human and mouse resistin genes and protein sequences share only approximately 60 % homology, which is less than most hormones conserved across species, the genes are syntenic, with the mouse gene encoding resistin being located at a similar distance from the insulin receptor gene. Unlike mouse resistin which is mainly expressed in adipocytes, human resistin is synthesized predominantly in monocytes and macrophages, especially in the visceral adipose tissue. Resistin’s e!ects are mediated via paracrine and endocrine mechanisms of action through a recep-tor on the surface of target cells that remains controversial. Others and our study has shown that resistin interacts with the Toll-like receptor 4 (TLR4), however other putative receptors such as an isoform of decorin, mouse receptor tyrosine kinase-like orphan receptor 1 (ROR1) and adenylyl cyclase-associated protein 1 (CAP1) have been also proposed. Downstream targets of resistin provide indirect evidence for its function in intracellular pathways, involving impairment of insulin signaling, response to in"ammation and proliferation. Despite the lack of in vivo data concerning the resistin receptor and signaling in primates or
