- 免疫学 免疫学 免疫学
- 神经学 神经学
背景情况:
- 奥克雷利祖马布 (OCR) 是一种抗CD20单克隆抗体,用于复发性复发性和原发性进展性多发性硬化症 (MS).
- 标准间隔剂量 (SID) 是OCR目前的使用方案.
研究的目的:
- 为了评估个人化ocrelizumab延长间隔剂量 (EID) 的有效性,在MS患者从SID切换后.
- 评估个性化剂量对临床和放射性结果的影响.
主要方法:
- 一项回顾性,观察性,单中心研究包括128名多发性硬化症患者.
- 在累计OCR剂量≥1200毫克后,稳定的患者被切换到EID,注射时间为CD19+27+记忆B细胞重新填充.
主要成果:
- 113名患者 (88.3%) 转换为EID,平均间隔为9.9个月.
- 没有发生临床复发;2名患者的残疾情况恶化.
- 观察到最小的新T2脑和脊髓病变,IgG和IgM度略有下降.
结论:
- 基于B细胞重组的个性化OCR剂量有效地延长了输液间隔,同时保持了疗效.

Cells of the Adaptive Immune Response
980
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...

Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
