Murine monoclonal antibodies (mAbs) are described that recognize the extracellular human interferon gamma receptor alpha-chain (IFN gamma R) and inhibit the binding to it of interferon gamma. The inhibitory activities (IC(50)s) of these mAbs, quantified by ...
B cells undergo a complex series of maturation and selection steps in the bone marrow and spleen during differentiation into mature immune effector cells. The tumor necrosis factor (TNF) family member B cell activating factor of the TNF family (BAFF) (BLyS ...
The TNF family ligand B cell-activating factor (BAFF, BLyS, TALL-1) is an essential factor for B cell development. BAFF binds to three receptors, BAFF-R, transmembrane activator and CAML interactor (TACI), and B cell maturation antigen (BCMA), but only BAF ...
A stepwise approach to the development of artificial O6-alkylguanine-DNA alkyltransferases (AGTs) and its application to the in vitro selection of antibodies with highly reactive cysteine residues are described. As a result of low reactivity of O6-alkylate ...
A role in thymic maturation for factors of the NF-kappaB family has long been suspected, but not yet proven. Transgenic mice with a lymphocyte-specific defect in NF-kappaB activation were produced by targeted expression of human IkappaB alpha. The thymic c ...
In animals, growth is regulated by the complex interplay between paracrine and endocrine signals. When food is scarce, tissues compete for nutrients, leading to critical resource allocation and prioritization. Little is known about how the immune system ma ...
