Interleukin (IL)-11 is a bone marrow fibroblast derived cytokine with a wide spectrum of activities in different biological systems. It has been shown that IL-11 supports the growth of certain types of plasmacytoma and hybridoma cells, enhances antigen-specific antibody responses, synergizes with IL-3 in supporting megakaryocyte colony formation, acts synergistically with IL-3 in shortening the G0 period of early progenitors, induces the synthesis of acute phase proteins, and inhibits lipoprotein lipase activity and adipocyte differentiation. The human IL-11 gene, which is localized at 19q13.3-13.4, consists of five exons and four introns. Initial biochemical characterization has identified a 151 kDa protein as the potential IL-11 binding subunit of the receptor complex. Because of the overlapping biological activities between IL-6 and IL-11, we compared the signal transduction pathways mediated by IL-6 or IL-11 in cell lines responsive to both cytokines. Results from protein tyrosine phosphorylation and immediate response gene expression suggest that there are convergent and divergent points along the signal transduction pathways utilized by IL-6 or IL-11. The IL-6 signal transducer, gp130, appears to be involved in the IL-11 mediated signaling. Other cytokines such as leukemia inhibitory factor, oncostatin M and ciliary neurotrophic factor have also been shown to utilize gp130 as a signal transducer. The significance of growth factor sharing common biological activities and signaling pathways will be discussed.

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...
T Cell Types and Functions01:24

T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...
Insulin: The Receptor and Signaling Pathways01:28

Insulin: The Receptor and Signaling Pathways

Insulin action is mediated through a receptor tyrosine kinase, akin to the IGF-1 receptor. The number of receptors per cell varies significantly, from 40 on erythrocytes to 300,000 on adipocytes and hepatocytes. The insulin receptor consists of linked α/β subunit dimers, forming a heterotetramer glycoprotein with two extracellular α subunits and two β subunits spanning the membrane. The α subunits inhibit the inherent tyrosine kinase activity of the β subunits, but this inhibition is released...
Type I Diabetes II: Pathophysiology01:26

Type I Diabetes II: Pathophysiology

Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...

Inflammatory Bowel Disease III: Crohn's Disease

Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
