Potential to deflect the flow of the other, such as MAPK JNK and ERK. The use of animal models of animal models are essential for the evaluation of potential therapeutic compounds.

The selection of an appropriate model and the time of administration of the drug may have a great impact on the results and the importance of human disease.
44 redundant signaling networks cytokines such networks have are redundant signaling pathways and complex. It is naive to think that ? blocking a kinase, especially behind the track can not lead to Nutlin-3 compensatory effects in other kinases that regulate the same genes. For example, the kinases upstream Rts of p38, such as MKK3, MKK6 and TAK1 regulate NF B ? and direct the signaling flow.45 46 escape physiological regulation of p38, the surprising observation that the decrease in CRP levels are temporarily despite adequate drug schl gt before that people have an inhibition mechanism of physiological inhibition of p38. CRP in the liver is dependent p38-Dependent cytokines such as IL-1 and regulates IL6.
47 A m Possible explanation Tion is that the production of CRP is not in the tissue with minimal effect ver Changed or reduced p38 inhibitors as can synthesize where central nervous system glial cells CRP. 48 is, however, not clear whether CRP production in the brain at levels significantly in plasma. Another interesting M Possibility is that CRP is produced fa P38 is independent Dependent. For example, without like receptor 4-induced IL-6 production in macrophages is independent Ngig of p38 or NF B activity.49 ? IL6 is a potent activator of protein production of the acute phase of hepatocytes. Another potent inducer of CRP and serum amyloid A is the endoplasmic reticulum stress. This cellular stress response Ren induced calcium and ATP or low exposure LPS.50 These factors impede ER function.

How many p38 inhibitors are hepatotoxic, a potential ER stress escape mechanism is not MAPK. The observation that not correlate to clinical responses to inhibitors of p38 with the kinetics of the PCR reaction, suggesting that the mechanism k Nnte not be really escape, but represents an alternative related signal transduction. R P38 in RA Ultimately, the M Possibility that p38 is not to be considered involved in the pathogenesis of rheumatoid arthritis. This seems unlikely, given the known functions of p38 and the richness of the pr Clinical and human s
