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.

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.

Enzyme activity during germination of different cereals: A review
Food reviews international (Print), 2018The germination process increases enzymatic activity. However, this does not occur in the same way in all cereals. It depends on the type of enzyme, the cereal, and the conditions of germination.

Seed germination traits can contribute better to plant community ecology
, 2016Analyses of functional traits have become fundamental tools for understanding patterns and processes in plant community ecology. In this context, regenerative seed traits play an important, yet overlooked, role because they largely determine the ability ...

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 ...

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 ...

HE terminal course is a bugaboo which is being seriously attacked by constructive thinkers, and I have no desire to divert attention from any effort that will contribute to its solution. The sooner we can determine exactly what should be taught to students who leave college at the end of their second year-not least of all in literature-the sooner we ...
