Cytokeratin 17 (CK17) is a member of the Cytokeratin subfamily of intermediate filament proteins (IF's). It is unique in that it is normally expressed in the basal cells of complex epithelia but not in stratified or simple epithelia. CK17 is expressed in the nail bed, hair follicle, sebaceous glands and other epidermal appendages. Antibody to CK17 is an excellent tool to distinguish myoepithelial cells from luminal epithelium of various glands such as mammary, sweat and salivary. CK17 is expressed in epithelial cells of various origins, such as bronchial epithelial cells and skin appendages. It may be considered an epithelial stem cell marker because CK17 Ab marks basal cell differentiation. CK17 can be useful when included in a panel of antibodies against TTF-1, napsin A, CK5&6, p63, and SOX-2 for diagnostic differentiation between lung adenocarcinoma (LADC) and lung squamous cell carcinoma (SCLC), especially for poorly-differentiated lung carcinoma. CK17 is expressed in SCLC much higher than in LADC. In breast carcinomas, approximately 20% of patients show no expression of ER, PR and Her2, which are defined as triple negative tumor. Eighty-five percent of the triple negative breast carcinomas immunoreact with basal cytokeratins including anti-CK17. Also important is that cases of triple negative breast carcinoma with expression of CK17 show an aggressive clinical course. The histologic differentiation of ampullary cancer, intestinal vs. pancreatobiliary, is very important for treatment. Usually anti-CK17 and anti-MUC1 immunoreactivity represents pancreatobiliary subtype whereas anti-MUC2 and anti-CDX-2 positivity defines intestinal subtype.

Mouse Interleukin 36 beta (IL-36B)is a member of the IL-1 family of proteins. It is a cytokine that binds to and signals through the IL1RL2/IL-36R receptor which in turn activates NF-kappa-B and MAPK signalling pathways in target cells linked to a pro-inflammatory response. IL-36B is synthesised in several cells including resting and activated monocytes, and B cells. The receptor for IL-36 beta is thought to be a combination of IL-1 Rrp2 and IL-1 RAcP. Interleukin 36 beta is one part of the IL-36 signalling system that is thought to be present in epithelial barriers and to take part in local inflammatory response; similar to the IL-1 system with which it shares the coreceptor IL1RAP. Interleukin 36 beta are involved in a number of fundamental biological processes such as stimulating production of interleukin-6 and interleukin-8 in synovial fibrobasts, articular chondrocytes and mature adipocytes, inducing expression of a number of antimicrobial peptides including beta-defensin 4 and beta-defensin 103 as well as a number of matrix metalloproteases , inducing the production of proinflammatory cytokines in bone marrow-derived dendritic cells (BMDCs), including IL-12, Il-1 beta, IL-6, TNF-alpha and IL-23, and activating p38 MAPK phosphorylation in BMDCs.Moreover, interleukin 36 beta may be involved in skin inflammatory response by acting on keratinocytes, dendritic cells, and indirectly on T cells to drive tissue infiltration, cell maturation and cell proliferation. It plays an important role in dendritic cell maturation by stimulating the surface expression of CD80, CD86 and MHC class II and inducing the production of IFN-gamma, IL-4 and IL-17 by T helper 1 (Th1) cells, cultured CD4+ T cells and splenocytes.

Mouse Interleukin-36 alpha(Il-36a)is a member of the IL-1 family.IL¬1 alpha,IL¬1 beta and IL-18 are potent inflammatory cytokines whose activities are dependent on heterodimeric receptors of the IL-1R superfamily, and which are regulated by soluble antagonists. Il36a is expressed in many cells, including monocytes, B cells, and T cells, immune system and fetal brains. Il36a is a cytokine that binds to and signals through the IL1RL2/IL-36R receptor which in turn activates NF-kappa-B and MAPK signaling pathways in target cells linked to a pro-inflammatory response. It is a part of the IL-36 signaling system that is thought to be present in epithelial barriers and to take part in local inflammatory response; similar to the IL-1 system with which it shares the coreceptor IL1RAP. It seems to be involved in skin inflammatory response by acting on keratinocytes, dendritic cells and indirectly on T cells to drive tissue infiltration, cell maturation and cell proliferation. It Induces the production of proinflammatory cytokines, including IL-12, Il-1 beta, IL-6, TNF-alpha and IL-23 in bone marrow-derived dendritic cells (BMDCs). Moreover, it is involved in dendritic cell maturation by stimulating the surface expression of CD80, CD86 and MHC class II and can induce the production of IFN-gamma, IL-4 and IL-17 by cultured CD4+ T cells and splenocytes. Il36a may play a role in proinflammatory effects in the lung: induces the expression of CXCL1 and CXCL2 in the lung, and the expression of TNF-alpha, IL-36c, IL-1A, IL-1B, CXCL1 and CXCL2 in isolated splenic CD11c+ alveolar macrophages. It may be involved in T cell maturation by stimulating the surface expression of CD40 and modestly CD80 and CD86 in splenic CD11c+ cells and CD4+ T cell proliferation.

The spectrin family of proteins were originally discovered as major components of the submembraneous cytoskeleton of osmotically lysed red blood cells (1). The lysed blood cells could be seen as clear red blood cell shaped objects in the light microscope and were referred to as red cell "ghosts". The major proteins of these ghosts proved to be actin, ankyrin, band 4.1 and several other proteins, including two major bands running at about 240kDa and 260kDa on SDS-PAGE gels. This pair of bands was named "spectrin" since they were discovered in these red blood cell ghosts (1). Later work showed that similar high molecular bands were seen in membrane preparations from other eukaryotic cell types. Work by Levine and Willard described a pair of about ~240-260kDa molecular weight bands which were transported at the slowest rate along mammalian axons (2). They named these proteins "fodrin" as antibody studies showed that they were localized in the sheath under the axonal membrane, but not in the core of the axon (2; fodros is Greek for sheath). Subsequently fodrin was found to be a member of the spectrin family of proteins, and the spectrin nomenclature is now normally used (3). Spectrins form tetramers of two alpha and two beta subunits, with the alpha corresponding to the lower molecular weight ~240kDa band and the beta corresponding to the ~260kDa or in some case much larger band. Most spectrin tetramers are about 0.2microns or 200nm long, and each alpha and beta subunit has a cell type specific expression pattern. The basic structure of each spectrin subunit is the spectrin repeat, which is a sequence of about 110 amino acids which defines a compact domain contain three closely packed alpha-helices. Each spectrin subunit contains multiple copies of this repeat, with 20 in each of the alpha subunits. The beta I-IV subunits each contain 17 spectrin repeats, while the beta V subunit, also known as beta-heavy spectrin, contains 30 of these repeats. The various subunits also contain several other kinds of functional domain, allowing the spectrin tetramer to interact with a variety of protein, ionic and lipid targets. The alpha-subunits each contain one calmodulin like calcium binding region and one Src-homology 3 (SH3) domain, an abundant domain involved in specific protein-protein interactions. The beta subunits all have a N-terminal actin binding domain and may also have one SH3 domain and one pleckstrin homology domain, a multifunctional type of binding domain which in beta I spectrin at least binds the membrane lipid PIP2 (5). Spectrins are believed to have a function in giving mechanical strength to the plasma membrane since the tetramers associate with each other to form a dense submembraneous geodesic meshwork (3). They also bind a variety of other membrane proteins and membrane lipids, and the proteins they bind to are therefore themselves localized in the membrane. Diseases may be associated with defects in one or other of the spectrin subunits (6). For example, some forms of hereditary spherocytosis, the presence of spherical red blood cells which are prone to lysis, can be traced to mutations in some of the spectrin subunits (7). The alpha-II subunit is widely expressed in tissues but, in the nervous system, is found predominantly in neurons. The antibody can therefore be used to identify neurons and fragments derived from neuronal membranes in cells in tissue culture and in sectioned material.
