A novel receptor involved in T-cell activation
Article Abstract:
An innovative glycoprotein with a relative molecular mass of 70,000 (Mr 70K) and a member of the immunoglobulin gene superfamily, designated SLAM, increases antigen-specific proliferation and cytokine production by T cells carrying the CD4 antigen. The greatest effects are seen on the production of interferon-gamma whereas no effect on the production of interleukin-4 and 5 is observed. Direct induction of the proliferation of CD4+ T-cells clones by SLAM is discussed.

Molecular basis for interaction of the protein kinase ZAP-70 with the T-cell receptor
Article Abstract:
An interface forming one of the two critical phosphotyrosine binding sites connected through a coiled coil of alpha-helices occurs in vivo in complex formed by association of tandem Sh2 domains of human ZAP-70 with a peptide derived from the zeta-subunit of the T-cell receptor. This structural observations for the complex formed provide an insight in to various mechanisms of molecular level activities of T-cell receptor antigen.

A motif in the alphabeta T-cell receptor controls positive selection by modulating ERK activity
Article Abstract:
A study of thymocytes is discussed with reference to the effect of positive and negative selection. The results reveal that a mutation in the alphabeta T-cell receptor which mediates selection changes ERK activity and controls positive selection.
