Annual Review of Immunology, 2012
Germinal centers (GCs) were described more than 125 years ago as compartments within secondary lymphoid organs that contained mitotic cells. Since then, it has become clear that this structure is the site of B cell clonal expansion, somatic hypermutation, and affinity-based selection, the combination of which results in the production of high-affinity ...

Radical History Review, 2023
AbstractThe idea of the Anthropocene has spread far beyond its origins in geology, becoming common in contemporary activist and intellectual circles. But who is responsible for the mounting disasters associated with the age of anthropos, and who should be made to pay reparations? What if the onset of the Anthropocene was tenaciously resisted in various

Cellular and Molecular Life Sciences (CMLS), 2002
Despite being relatively insensitive to environmental insult, the spore is responsive to low concentrations of chemical germinants, which induce germination. The process of bacterial spore germination involves membrane permeability changes, ion fluxes and the activation of enzymes that degrade the outer layers of the spore.

Annual Review of Immunology, 1994
Germinal centers develop in the B cell follicles of secondary lymphoid tissues during T cell-dependent (TD) antibody responses. The B cells that give rise to germinal centers initially have to be activated outside follicles, in the T cell-rich zones in association with interdigitating cells and T cell help.

Current Opinion in Microbiology, 2003
The germination of dormant spores of Bacillus species is the first crucial step in the return of spores to vegetative growth, and is induced by nutrients and a variety of non-nutrient agents. Nutrient germinants bind to receptors in the spore's inner membrane and this interaction triggers the release of the spore core's huge depot of dipicolinic acid ...
