In summer 2025, the SARS-CoV-2 JN.1 sublineage became dominant with more resistant variants, such as XFG, LP.8.1, and NB.1.8.1. COVID-19 mRNA boosters were therefore updated for the 2025–2026 season ...
在这项最新研究中,研究团队确定了甲羟戊酸通路的代谢中间产物法尼基焦磷酸(FPP)是一种内源性警报素,它通过角质形成细胞(Keratinocyte)来源的 IL-6 和 CCL20 增强 IgG 抗体应答。这一信号轴增强了滤泡辅助 T ...
EAE-induced neuroinflammation. Using immuohistochemistry, flow cytometry, and single-cell RNAseq of doublets to interrogate cell-cell interactions, the authors provide solid evidence that macrophages, ...
