 |  Activation of Csk by cAMP-dependent Protein Kinase Inhibits Signaling through the T Cell Receptor  
Interaction of T cell receptor with specific antigen in the context of MHC II activates a signal transduction pathway that leads to T cell activation. In the T cell receptor signaling pathway, the src family kinases Lck and Fyn are activated to phos ... |

 | Adaptive Immune Response to Cancer Cells
Tumours arise and progress within a microenvironment that is replete with healthy, non-transformed cells. Crosstalk between normal and neoplastic cells influence various stages of carcinogenesis. Cancer-bearing hosts can frequently mount innate and a ... |

| Adaptor Proteins and Signal Transduction in T-cells
Activation of the Engagement of the TCR by peptide/MHC complexes results in the activation of a number of protein-tyrosine kinases, including members of the src family, LCK and FYN-T, and syk family, ZAP-70 and SYK. Activated protein-tyrosine kinases ... |

 | Adhesion Molecules on Lymphocyte
B cell and T cell lymphocytes interact with a variety of cells as part of their immune function, circulating and homing in on specific stimuli in tissues like inflammatory signals. The interaction of lymphocytes with other cell types like vascular en ... |

| Ahr Signal Transduction Pathway
The Ah receptor, bHLH/PAS transcription factor, upon binding of an agonist such as 2,3,7,8-tetrachlorodibenzo-p-dioxin translocates into the nucleus and heterodimerizes with the transcription factor ARNT. The Ahreceptor/ARNT heterodimer binds to diox ... |

 | Alternative Complement Pathway
The complement system of plasma proteins is an important part of the immune system that forms a cascade of factors that lyses foreign cells. There are two branches of the complement system, the classical pathway that is initiated by antibody-antigen ... |

 | Anthrax Toxin Mechanism of Action
One of the key causes of anthrax virulence is the production of three specific factors by the gram-positive spore forming bacteria Bacillus anthracis. Even with successful antibiotic treatment, anthrax toxins can remain in the circulation and cause ... |
