Leukemia inhibitory factor (LIF) is a pleotropic glycoprotein that belongs to the IL6 family of cytokines. It is secreted by many cell types such as, fibroblasts, macrophages, T cells, monocytes, liver cells, osteoblasts and cells of endometrium. LIF interacts with a heterodimeric receptor composed of two subunits, gp130 and gp190. A variety of signal transduction pathways are triggered in response to LIF including ERK/MAPK, JAK1, PI3K, STAT3, Jun-cFos and NF-κB. The various functions of LIF include proliferation of adult human T cells, maintenance of pluripotency of embryonic stem cells and inhibition of leukemic ell differentiation. Reports also indicate the important role of LIF in lactation, tissue regeneration after brain and spinal cord injury, muscle regeneration and motor neuron functions. Anti-Leukemia Inhibitory Factor recognizes mouse leukemia inhibitory factor. It shows less than 5% cross-reactivity with recombinant human LIF.
Immunogen

STAT3 is the key mediator of apoptosis in mammary gland. We demonstrate here that LIF is the physiological activator of STAT3, because in involuting mammary glands of Lif(-/-) mice, pSTAT3 is absent and the STAT3 target, C/EBPdelta, is not upregulated.
Leukemia inhibitory factor (LIF) is an important regulator of skeletal muscle regeneration and has been suggested to be mitogenic for myogenic cells because it has been shown to increase the quantity of myoblast cells grown in culture over extended periods

Leukaemia inhibitory factor (LIF) is one of a growing number of cytokines that cannot be readily categorized according to its functions. Rather, these pleiotropic hormones have diverse and often overlapping effects on a multitude of cell types: for example, LIF
LIF, a member of the IL6 family of cytokine, displays pleiotropic effects on various cell types and organs. Its critical role in stem cell models (e.g.: murine ES, human mesenchymal cells) and its essential non redundant function during the implantation
At the heart of lineage commitment within the adaptive immune response is the intrinsic genetic plasticity of the naive peripheral T lymphocyte (T cell). Primary activation by presentation of cognate antigen is coupled to rapid T-cell cycling and progressive epigenetic
