Agonistic humanized anti-CD134(OX40) antibodies improve T effector cell function by depleting T regulatory cells in vitro.  This approach has great potential for augmenting cancer therapy! “Antibodies Targeting Human OX40 Expand Effector T Cells and Block Inducible and Natural Regulatory T Cell Function” K.S. Voo, Y.J. Liu, et al. (2013) J Immunol 191: 3641-3650. PMID: 24014877

The BTLA(CD272)-HVEM(CD270) pathway is an important regulatory mechanism for gamma/delta T cell proliferation. A subset of gamma/delta T cells can be induced to have potent anti-Lymphoma activity.  The amount of BTLA present on cell surface of these cells inversely correlates with their degree of differentiation. Blockade of this pathway can increases T cell signaling ability,

Stem Cell Factor (SCF) can activate Lung Mast cells through CD117 (c-kit) to become more responsive to IgE challenge in vitro.  Up regulation of CD63 can be used to track this activation “Heterogeneity in the responses of human lung mast cells to stem cell factor” A. Lewis, J. Wan, B. Baothman, P. N. Monk, S.
