General description

Cluster of differentiation 28 (CD28) antigen is a co-stimulatory receptor expressed in naive T-cells. It contains a short cytoplasmic tail and two proline-rich motifs.

Immunogen

Peptide with sequence KEKHLCHTQSSPK, from the internal region of the protein sequence according to NP_031668.3

Biochem/physiol Actions

Cluster of differentiation 28 (CD28) antigen has a role in T-cell activation, proliferation, survival and function. It modulates thymic development, peripheral homeostasis and the suppressive functions of regulatory T cells. CD28 has a role in signal transduction and is involved in activating many adaptor proteins.

Effective therapeutic interventions for chronic, idiopathic lung diseases remain elusive. Normalized T-cell function is an important contributor to spontaneous resolution of pulmonary sarcoidosis. Up-regulation of inhibitor receptors, such as programmed death-1 (PD-1) and its ligand, PD-L1, are important inhibitors of
