Any process that modulates the frequency, rate or extent of lymphocyte activation.

The process whose specific outcome is the progression of the midbrain over time, from its formation to the mature structure. The midbrain is the middle division of the three primary divisions of the developing chordate brain or the corresponding part of the adult brain (in vertebrates, includes a ventral part containing the cerebral peduncles and a dorsal tectum containing the corpora quadrigemina and that surrounds the aqueduct of Sylvius connecting the third and fourth ventricles).

Stops, prevents or reduces the activity of a phospholipase, an enzyme that catalyzes of the hydrolysis of a glycerophospholipid.

The process whose specific outcome is the progression of the hindbrain over time, from its formation to the mature structure. The hindbrain is the posterior of the three primary divisions of the developing chordate brain, or the corresponding part of the adult brain (in vertebrates, includes the cerebellum, pons, and medulla oblongata and controls the autonomic functions and equilibrium).

Responses induced by any reactive oxygen species, including singlet oxygen, superoxide, and oxygen free radicals.

Responses induced by superoxide (the anion, oxygen-, formed by addition of one electron to dioxygen (O2) or any compound containing the superoxide anion).

Response induced by any oxygen radical (any oxygen species that carries a free electron, examples include hydroxyl radicals and the superoxide anion).

The directed movement of nucleotide-sugars into, out of, within or between cells. Nucleotide-sugars are any nucleotide in which the distal phosphoric residue of a nucleoside 5'-diphosphate is in glycosidic linkage with a monosaccharide or monosaccharide derivative.

The post-translational removal of peptide sequences from within a protein sequence.

The lengthening of the distance between poles of the spindle.

The directed movement of pyrimidine nucleotide-sugars into, out of, within or between cells. Pyrimidine nucleotide-sugars are pyrimidine nucleotides in glycosidic linkage with a monosaccharide or monosaccharide derivative.
