Three different pathways work on different mechanisms to achieve apoptosis. All three of these pathways converge at the same terminal pathway, which results in the sequential degradation of cellular organelles. 1. Extrinsic or death receptor pathway The extrinsic pathway that initiates apoptosis involves ...
This kind of scaffolding molecule has been found in other pathways as well, and may turn out to be a common mechanism for keeping signaling pathways rapid and specific. An interesting aside to the mating pathway is that a second pathway, called the filamentous growth pathway, uses some of ...

The compromised immune response in the gastrointestinal mucosa, and the suspected disruptions to the gut microbiome, are primarily responsible for the pathogenesis of inflammatory bowel disease (IBD). Excessive inflammation of the GI tract activates a network of signaling pathways, such as RANKL/RANK/...
longitudinal axis. The nervous systems of organisms with bilateral symmetry coordinate and control the left and right sides, and the signaling pathways are unidirectional. Human beings, monkeys, chickens, dogs, rats, lizards, butterflies, and worms are all examples of organisms with bilateral symmetry...

Primary databases such as KEGG can be used to obtain information on metabolic and signaling pathways in various organisms. References Baker, W., Camon, E., Hingamp, P., Sterk, P., Stoesser, G., & Tuli, M. A. (2000). The EMBL Nucleotide Sequence Database. Nucleic Acids Research, 28...
of these receptors is involved in intracellular signaling pathways when an antigen binds to it. (Ref.5) The binding of antigen to the B cell leads to the latter’s activation (with the aid of a helper T cell). The activated B cell will proliferate and differentiate into an antibody-...
This allows gap junctions to participate in cell signaling by controlling the flow of molecules across signaling pathways.Gap junctions are capable of responding in a variety of ways when subjected to a wide range of stimuli and are dynamically controlled, either through fast processes such as ...
