Purine enzymes and immune function.

R W Watts

    Clinical Biochemistry
    |February 1, 1983
    PubMed
    Summary
    This summary is machine-generated.

    Immune function relies on lymphocytes responding to antigens, a process requiring purine nucleotides for cell division. This review explores how cell surface events increase purine synthesis and how intracellular messengers modulate these pathways.
