Dictionary » C » Cytokine CytokineCytokine (Science: biochemistry) small proteins or biological factors (in the range of 5-20 kD) that are released by cells and have specific effects on cell-cell interaction, communication and behaviour of other cells. Not really different from hormones, but the term tends to be used as a convenient generic shorthand for interleukins, lymphokines and several related signalling molecules such as TNF and interferons. Generally growth factors would not be classified as cytokines, though tgf is an exception. Rather an imprecise term. Chemokines are a subset of cytokines. ![]()

Results from our forumcortisol and B/T-cells... the reported effects of cortisol on wound healing do not involve B and T cells, and have more to do with reduced effect of neutrophil-associated cytokine functions. Also, apparently only few groups have noticed this phenomenom, so I'm not sure if the effect is that profound anyway. Cortisol (and ...

Re: ?{REGENERATION}? Is it possible ???!!... But if the dna "blueprints" are still there, we should be able to create an environment (albeit complex) to facilitate regeneration. The cytokine and hormone environment has been brought up in the literature to be conducive to fibrosis. I believe that it is cytokines, though a different ...

?{REGENERATION}? Is it possible ???!!... challenging task to artificially create an environment where humans could regenerate back a limb, with all the issues of genetic regulation and cytokine/hormone environment that is reguired for it to happen properly.

bystander cell - bystander effect (fibroblasts)... but I think I got a clue: Bystander cells, are cell not involved in a process, but are affected by it. E.g. uninvolved T-cells or B-cells through cytokine secretion. Is this correct? Does somebody have a more accurate deffinition? Can fibroblasts be called bystander cells in terms of vaccination? ...

Re:... of infection switch to CD45RO+ memory phenotype if they encounter their specific MHC:peptide complex. Depending on the TCR signaling, prevaling cytokine environment, and cell-cell interactions, the memory cells can be divided to central memory cells or effector memory cells, which in turn can ...
