negative regulation of B cell activation

negative regulation of B-lymphocyte activation

Any process that stops, prevents or reduces the rate of B cell activation.

The branch of the pentose-phosphate shunt which involves the oxidation of glucose 6-P and produces ribulose 5-P, reduced NADP+ and carbon dioxide (CO2).

Catalysis of the reaction: CTP + N-acylneuraminate = diphosphate + CMP-N-acylneuraminate.

The branch of the pentose-phosphate shunt which does not involve oxidation reactions. It comprises a series of sugar phosphate interconversions, starting with ribulose 5-P and producing fructose 6-P and glyceraldehyde 3-P.

Any substance to which an electron may be transferred.

Any molecular entity that serves as an electron acceptor and electron donor in an electron transport system.

Any metabolic process involving the breakdown of complex substances into smaller products, including the breakdown of carbon compounds with the liberation of energy for use by the cell or organism.

The breakdown into simpler components of a macromolecule, any large molecule including proteins, nucleic acids and carbohydrates.

positive regulation of calcium-mediated signaling

Any process that activates or increases the rate of calcium-mediated signaling.

The energy-requiring part of metabolism in which simpler substances are transformed into more complex ones, as in growth and other biosynthetic processes.

A series of molecular signals initiated by the cross-linking of an antigen receptor on a B- or T cell.

The formation from simpler components of macromolecules, large molecules including proteins, nucleic acids and carbohydrates.

The process whose specific outcome is the progression of the mammary gland over time, from its formation to the mature structure. The mammary gland is a large compound sebaceous gland that in female mammals is modified to secrete milk.

A series of molecular signals initiated by the cross-linking of an antigen receptor on a T cell.

A series of molecular signals initiated by the cross-linking of an antigen receptor on a B cell.
