Target Information

Leukemia inhibitory factor (LIF) is a 20 kDa protein belonging to the IL-6 receptor family. It binds to a heterodimeric receptor composed of a LIF-specific subunit (gp190 or LIFR) and gp130, which is shared with other IL-6 family members. LIF expression occurs in various tissues including thymus, lung, and neuronal tissue. It can be up-regulated by pro-inflammatory cytokines such as TNFα and IL-17, and elevated levels have been observed in rheumatoid arthritis, neural injury, systemic inflammation, and tuberculosis. LIF is known for inhibiting differentiation of embryonic stem cells in mice and supporting stem cell self-renewal. Human and mouse LIF share 79% sequence homology, but the inhibition of stem cell differentiation is mouse-specific.
