Immunohistochemical analysis of paraffin-embedded human Brain‌ tissue using Leptin antibody was performed. The section was pretreated using high-temperature and high-pressure mediated EDTA antigen retrieval buffer (pH 9.0), for 5 minutes. The tissues were incubated with primary antibody (HY-P81241, 1:200 dilution) overnight at 4°C. Detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. The tissues were counterstained with hematoxylin and mounted with neutral balsam mounting medium.

Tyramide signaling amplification based immunofluorescence was performed on paraffin-embedded human Brain tissue using Leptin antibody. Antigen retrieval was performed in EDTA buffer pH 9.0 (95 °C, 20 min) followed by cooling to RT. Then incubated with primary antibody (HY-P81241, 1:200 dilution) overnight at 4°C and HRP conjugated secondary antibody for 10 minutes. Fluorescence was then developed with Vari Fluor 532 TSA (200×)（HY-D1832）. The tissues were counterstained with DAPI and mounted with Anti-fade mounting medium.

Background

Function：Key player in the regulation of energy balance and body weight control. Once released into the circulation, has central and peripheral effects by binding LEPR, found in many tissues, which results in the activation of several major signaling pathways (PubMed:15899045, PubMed:17344214, PubMed:19688109). In the hypothalamus, acts as an appetite-regulating factor that induces a decrease in food intake and an increase in energy consumption by inducing anorexinogenic factors and suppressing orexigenic neuropeptides, also regulates bone mass and secretion of hypothalamo-pituitary-adrenal hormones. In the periphery, increases basal metabolism, influences reproductive function, regulates pancreatic beta-cell function and insulin secretion, is pro-angiogenic for endothelial cell and affects innate and adaptive immunity (By similarity) (PubMed:11460888, PubMed:19688109, PubMed:24340098, PubMed:25060689, PubMed:8589726). In the arcuate nucleus of the hypothalamus, activates by depolarization POMC neurons inducing FOS and SOCS3 expression to release anorexigenic peptides and inhibits by hyperpolarization NPY neurons inducing SOCS3 with a consequent reduction on release of orexigenic peptides (By similarity). In addition to its known satiety inducing effect, has a modulatory role in nutrient absorption. In the intestine, reduces glucose absorption by enterocytes by activating PKC and leading to a sequential activation of p38, PI3K and ERK signaling pathways which exerts an inhibitory effect on glucose absorption (PubMed:24340098). Acts as a growth factor on certain tissues, through the activation of different signaling pathways increases expression of genes involved in cell cycle regulation such as CCND1, via JAK2-STAT3 pathway, or VEGFA, via MAPK1/3 and PI3K-AKT1 pathways (By similarity) (PubMed:17344214). May also play an apoptotic role via JAK2-STAT3 pathway and up-regulation of BIRC5 expression (PubMed:18242580). Pro-angiogenic, has mitogenic activity on vascular endothelial cells and plays a role in matrix remodeling by regulating the expression of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) (PubMed:11460888). In innate immunity, modulates the activity and function of neutrophils by increasing chemotaxis and the secretion of oxygen radicals. Increases phagocytosis by macrophages and enhances secretion of pro-inflammatory mediators. Increases cytotoxic ability of NK cells (PubMed:12504075). Plays a pro-inflammatory role, in synergy with IL1B, by inducing NOS2 which promotes the production of IL6, IL8 and Prostaglandin E2, through a signaling pathway that involves JAK2, PI3K, MAP2K1/MEK1 and MAPK14/p38 (PubMed:15899045, PubMed:19688109). In adaptive immunity, promotes the switch of memory T-cells towards T helper-1 cell immune responses (By similarity). Increases CD4(+)CD25(-) T-cell proliferation and reduces autophagy during TCR (T-cell receptor) stimulation, through MTOR signaling pathway activation and BCL2 up-regulation (PubMed:25060689)

Subcellular Localization：Secreted

Expression：
Tissue_specificity:Adipose tissue is the main source of leptin. It is also produced by other peripheral tissues such as the skeletal muscle (PubMed:12448771, PubMed:16052473, PubMed:7789654) . Expressed by intercalated and striated tracts of submandibular and parotid salivary gland intralobular ducts (PubMed:12448771) . Detected by fundic epithelium of the gastric mucosa (PubMed:10896907) . Secreted into blood and gastric juice (PubMed:10896907)

Induction:Induced by secretin

Subunit：Interacts with SIGLEC6

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
