Target Information
Leukemia inhibitory factor (LIF) is a 20 kDa protein belonging to the IL-6 receptor family. It binds to a heterodimeric membrane receptor composed of a LIF-specific subunit (gp190 or LIFR) and the shared subunit gp130. LIF is expressed in various tissues including thymus, lung, and neuronal tissue, and can be up-regulated by pro-inflammatory cytokines such as TNFα and IL-17. Elevated LIF levels have been observed in rheumatoid arthritis, neural injury, systemic inflammation, and tuberculosis. It is best known for inhibiting differentiation of embryonic stem cells in mice, contributing to stem cell self-renewal. Human and mouse LIF share 79% sequence homology and exhibit cross-species activity, though stem cell differentiation inhibition appears mouse-specific.
