The directed killing of a target cell by an immune cell.

regulation of T-helper cell differentiation

Any process that modulates the frequency, rate or extent of T-helper cell differentiation.

negative regulation of T-helper cell differentiation

Any process that stops, prevents or reduces the rate of T-helper cell differentiation.

tyrosine phosphorylation of Stat3 protein

The process of introducing a phosphoric group to a tyrosine residue of a Stat3 protein.

positive regulation of T-helper cell differentiation

Any process that activates or increases the rate of T-helper cell differentiation.

Catalysis of the ligation of two substances with concomitant breaking of a diphosphate linkage, usually in a nucleoside triphosphate. Ligase is the systematic name for any enzyme of EC class 6.

regulation of T-helper 1 cell differentiation

Any process that modulates the frequency, rate or extent of T-helper 1 cell differentiation.

ligase activity, forming carbon-oxygen bonds

Catalysis of the ligation of two substances via a carbon-oxygen bond with concomitant breakage of a diphosphate linkage, usually in a nucleoside triphosphate.

ligase activity, forming aminoacyl-tRNA and related compounds

positive regulation of T-helper 1 cell differentiation

Any process that activates or increases the rate of T-helper 1 cell differentiation.

ligase activity, forming carbon-sulfur bonds

ligase activity, forming carbon-sulphur bonds

Catalysis of the ligation of two substances via a carbon-sulfur bond with concomitant breakage of a diphosphate linkage, usually in a nucleoside triphosphate.

The assembly of DNA, histone proteins, and other associated proteins into chromatin structure, beginning with the formation of the basic unit, the nucleosome, followed by organization of the nucleosomes into higher order structures, ultimately giving rise to a complex organization of specific domains within the nucleus.

regulation of T-helper 2 cell differentiation

Any process that modulates the frequency, rate or extent of T-helper 2 cell differentiation.
