概括

进激素 (PGRN) 在全身性红斑狼 (SLE) 发病过程中起作用. 在小鼠SLE模型中,PGRN淘汰小鼠在小鼠SLE模型中显示炎症和损伤减少,表明PGRN调解SLE发病.

科学领域:

免疫学免疫学免疫学
病理学病理学病理学

背景情况:

进激素 (PGRN) 参与免疫和炎症反应.
在全身性红斑狼 (SLE) 中观察到较高的PGRN水平,被认为是疾病活动的潜在生物标志物.
对于PGRN在SLE发病过程中的确切作用仍然不完全理解.

研究的目的:

调查前列腺素 (PGRN) 在全身性红斑狼 (SLE) 病变发生过程中的潜在参与.

主要方法:

在野生型 (WT) 和PGRN淘汰 (PGRN-/-) 小鼠中使用原始注射诱导SLE的小鼠模型.
每两周收集一次血清样本,以测量抗双链DNA (anti-dsDNA) 抗体,免疫球蛋白G (IgG) 和炎症因素.
在5个月后,分析了脏病变和脏T细胞亚型.

主要成果:

与普里斯坦注射后的WT小鼠相比,PGRN淘汰赛小鼠的抗dsDNA抗体和IgG水平明显较低.

The JAK-STAT Signaling Pathway

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...

Abnormal Proliferation

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

The Intrinsic Apoptotic Pathway

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
