Development of B Cell Memory in Malaria

development of feminist poetics in adrienne rich

اشعار ریچ، به عنوان اشعاری که همیشه در حال تغییر و دگرگونی هستند، تجسمی از رشد و دگرگونیِ انسان هستد. پایان نامه ی حاضر، با تمرکز بر روی مراحل سیر شعری ریچ از تغییری در دنیا به عکس هایی فوری از یک عروس، سپس به شیرجه به درون کشتی شکسته و در نهایت به صبری عجیب مرا تا اینجا آورده، به بررسی این مراحل در قالب نظر شوالتر در رابطه با سه مرحله ی پیشرفت ادبی زنان یعنی مرحله ی زنانه، زن گرا و زن محور می پ...

Malaria-associated atypical memory B cells exhibit markedly reduced B cell receptor signaling and effector function

Protective antibodies in Plasmodium falciparum malaria are only acquired after years of repeated infections. Chronic malaria exposure is associated with a large increase in atypical memory B cells (MBCs) that resemble B cells expanded in a variety of persistent viral infections. Understanding the function of atypical MBCs and their relationship to classical MBCs will be critical to developing e...

Development and maintenance of a B220- memory B cell compartment.

We have recently demonstrated that a novel somatically mutated B220(-) memory B cell subset rapidly dominates the secondary immune response to (4-hydroxy-3-nitrophenyl) acetyl (NP). Upon adoptive transfer with Ag, B220(+)NP(+) memory B cells produce large numbers of B220(-)NP(+) B cells that can rapidly differentiate into plasma cells. Therefore, it is not clear whether the novel B220(-) memory...

The Acquisition of Human B Cell Memory in Response to Plasmodium Falciparum Malaria

Immunity to Plasmodium falciparum (Pf), the most deadly agent of malaria, is only acquired after years of repeated infections and appears to wane rapidly without ongoing exposure. Antibodies (Abs) are central to malaria immunity, yet little is known about the B‐cell biology that underlies Pf‐specific humoral immunity. To address this gap in our knowledge we carried out a year‐long prospective s...
