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.

The article discusses a study by geneticist Steven Penfield and colleagues in the journal "Proceedings of the National Academy of Sciences USA" that found the flowering plant Arabidopsis passes down its temperature memories to its seeds to prepare them for incoming spring weather conditions.

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.

Summary: Using a set of surface markers Including igD and CD38, human tonsillar B cells were classified into discrete subpopulations. Molecular and functional analysis allowed us to identify: i) two sets of naive B cells (Bml and Bm2); ii) germinal center founder cells (Bm2′); iii) an obscure population of germinal center B cells, displaying a high ...

Neurology, 1971 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 ...

Germination is the first crucial step in the life cycle of obligate root parasitic Orobanchaceae, which cannot survive on their own. Therefore, germination of the tiny seeds with minimal reserves should occur only near host roots. These parasites detect the presence of hosts by using root-derived signalling molecules belonging to several distinct ...
