概括

在毒素免疫疗法 (VIT) 中,乳腺细胞 (MCs) 转向耐受性,当用IL-33进行原始化时. 这种原始化促进了诱导耐受性的细胞因子,这表明MCs指导免疫反应对Hymenoptera毒.

科学领域:

免疫学免疫学免疫学
过敏研究研究过敏
细胞生物学细胞生物学

背景情况:

脱敏包括将免疫反应从2型炎症转移到免疫耐受性.
毒素免疫疗法 (VIT) 用虫毒素和诱导介质素-33 (IL-33) 的释放.
巨细胞 (MCs) 在调解这种免疫反应开关中的作用需要研究.

研究的目的:

在模仿毒素免疫疗法 (VIT) 的条件下,研究IL-33和黑虫毒素对杆细胞 (MC) 细胞因子概况的影响.
为了确定乳腺瘤细胞 (MCs) 是否有助于在脱敏治疗期间从炎症转向耐受性的免疫切换.

主要方法:

人类乳腺细胞系 (LAD2) 和初级人体皮肤MCs用IL-33和黄虫毒素或化合物48/80进行刺激,有或没有IL-33原始化.
分析了细胞表面标记物表达,分泌的细胞因子 (IL-2,IL-5,IL-6,IL-13,TNF-α,TGF-β1) 和c-kit酸化.
进行了c-kit的抑制和刺激,以评估其在MC反应中的作用.

主要成果:

没有受孕的MCs分泌了促炎和2型细胞因子 (IL-2,IL-5,IL-6,IL-13,TNF-α) 和化c-kit.
主要分泌的是促进耐受性的细胞因子TGF-β1,具有减少的促炎性细胞因子,较少的c-kit酸化和较高的c-kit表面表达.
抑制c-kit模仿了IL-33原始效应,这表明c-kit信号在MC极化中的作用.

结论:

通过ST2和c-kit相互作用,长时间暴露于IL-33会使MCs在脱敏过程中倾向于产生促进耐受性的细胞因子.
乳腺母细胞 (MCs) 在指导黑虫毒素脱敏治疗期间的免疫反应类型中发挥着重要作用.

T Cell Types and Functions

T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Differentiation of Common Myeloid Progenitor Cells

Differentiation of Common Myeloid Progenitor Cells

Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
