Bombinin-Like Peptide (BLP-1) is an antimicrobial peptide from Bombina species.
IC50 Target
Bacterial[1]
体外研究 (In Vitro)
Bombinin-like peptides, BLP-1, 2, 3 share considerable, but not complete, homology with bombinin, an antimicrobial, hemolytic peptide first isolated from the skin of Bombina uariegata. The BLPs have been assayed for antibiotic and hemolytic activity and found to be more potent than magainin 2 (a related antimicrobial peptide from Xenopus laeuis) in their ability to kill bacteria[1].

V-set and transmembrane domain-containing protein(VSTM)家族是跨膜免疫球蛋白(Ig)超家族。其在结构上与B7-like免疫调节蛋白相似,并且拥有IgV-like和/或IgC-like胞外域。VSTM家族由8种蛋白组成:VSTM1v1、VSTM1v2、VSTM2a、VSTM2b、VSTM2L、VSTM3、VSTM4和VSTM5。据文献报道,VSTM家族成员与免疫细胞、脂肪细胞和神经元细胞的内在功能调节相关。目前大部分关于VSTM家族的研究都集中于其免疫功能上,例如,已证明VSTM1和VSTM4在巨噬细胞的激活中发挥积极或消极的作用。VSTM3(TIGIT、VSIG9)作为共抑制受体,可抑制T细胞和NK细胞的细胞因子产生。而与其他的免疫调节VSTM家族成员不同,VSTM2与脂肪生成过程中的脂肪前体调节有关。

生物活性
Glucagon-like peptide 1 (1-37), human (TFA) is a highly potent agonist of the GLP-1 receptor.
IC50 Target
GLP-1 receptor[1].
体外研究 (In Vitro)
Glucagon-like peptide-1 (GLP-1) is produced by the posttranslational processing of proglucagon and acts as a regulator of various homeostatic events. GLP-1(1-37) is more stable than GLP-1(7-37), with 94.7% of the initial amount of peptide left after a 4h exposure to mouse serum. GLP-1(1-37) is confirmed to be a highly potent agonist of the GLP-1 receptor (GLP-1R) by measuring the expression of the luciferase reporter gene expression in transiently transfected human embryonic kidney (HEK293) cells[1].
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究 (In Vivo)
GLP-1(1–37) decreases glycemic excursion in a dose-dependent. The administration of GLP-1(1–37) or GLP-1(7–37) markedly decrease blood glucose levels at 15 min and 30 min compared with the control group[1].

Cell Assay [1]
HEK293 cells (5×104) are seeded in a 96-well plate and transiently cotransfected with the GLP-1R plasmid and the CRE-luciferase reporter plasmid. After a 48 h transfection, different concentrations of GLP-1(1–37) or GLP-1(7–37) (TFA) are added, and the cells are incubated for 5 h. The cells are harvested for a luciferase assay using a luciferase assay[1].
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Animal Administration [1]
Mice[1]
The normal KM mice are fasted for 16 h before the administration (i.p.) of GLP-1 and glucose. GLP-1(1-37) (25 nmol/kg) with or without exendin(9-39) (250 nmol/kg) is given in combination with glucose (4 g/kg). GLP-1(7-37) (25 nmol/kg) with or without exendin(9-39) (250 nmol/kg) is also administrated in combination with glucose (4 g/kg). The control group is treated with saline (NaCl, 9 g/L) and glucose (4 g/kg). The IPGTT is carried out at 0, 15, 30 and 60 min after glucose and protein administration, and the blood glucose levels are measured as described above[1].
