抗体对我们来说并不陌生，它是免疫系统，用来识别和中和外来入侵者，如细菌、病毒的重要武器。然而，最近一项发表在《科学》杂志上的新研究，却揭示了一个令人意外的现象。 肠道中的某些共生菌，不仅不怕抗体的攻击，反而能够将抗体分解。

你发现了吗？我们的身体里有一支强大的‘免疫军团’，它们由五位超级战士组成，每天都在守护着我们的健康。你知道吗？免疫球蛋白（Ig）是这些战士的武器，它们不仅能识别和中和病原体，还能记住曾经遇到过的敌人，为我们的免疫系统提供长期的保护。今天，让我们一起解码免疫球蛋白的奥秘，看看它们是如何成为我们健康的‘守护神’的。

其中，流式细胞术用于分析各类细胞群体，如造血干细胞和祖细胞群体（HSPCs）、不同发育阶段的 T 细胞和 B 细胞等，精确检测细胞数量和比例的变化；酶联免疫吸附测定（ELISA）则用于测定血浆中各类抗体和蛋白的浓度，包括免疫球蛋白（IgM、IgA、IgG 等）、甲 ...

Immunoglobulin G (IgG) marks microbes so other cells can recognize and deal with them IgM specializes in killing bacteria IgA congregates in fluids, such as tears and saliva, where it protects ...

免疫球蛋白分为五类，即免疫球蛋白G（IgG）、免疫球蛋白A（IgA）、免疫球蛋白M（IgM）、免疫球蛋白D（IgD）和免疫球蛋白E（IgE）。 抗体：是机体 ...

A structural analogue of the inhibitory neurotransmitter γ-aminobutyric acid (GABA), gabapentin is a first line treatment for neuropathic pain and is effective for a variety of neuropathic pain ...

Ig serum concentrations were determined by nephelometry (Behring Nephelometer; normal ranges: IgG 7–16 g/L, IgM 0.4–2.3 g/L, IgA 0.7–4 g/L). ANCA staining patterns were assessed by indirect ...

The analysis of memory B-cell subsets was performed using a supervised selection strategy. A total of 5,000 iterations were performed using CD19, CD20, CD21, CD27, IgD, IgM, IgA and IgG parameters and ...
