Multiple sclerosis(MS)is the most common chronic disease of the central nervous system(CNS)in young adults and represents the first cause of severe handicap,originally non-traumatic(Oh et al.,2018).MS is chara cterized by the infiltration of auto reactive lymphocytes specific to myelin through the blood-brain barrier,which results in the appearance of inflammatory demyelinating lesions caused by the death of the central nervous system myelinating cells,oligodendrocytes(Oh et al.,2018).There is a prevalence sexual with a ratio of three times more affected women than men.

The combination of defective immune tolerance and external triggers is thought to underlie the pathophysiology of autoimmune hepatitis.1,2 Some polymorphisms associated with susceptibility to autoimmune hepatitis have been reported,and some cases have been described in patients with monogenic primary immune deficiencies or systemic diseases.

AIM： To analyse αv integrin expression induced by gas- trin in pancreatic cancer ***： αv integrin mRNA expression in human pan- creatic cancer cells was analysed using a ＂cancer genes＂ array and confirmed by real-time reverse transcription- polymerase chain reaction （PCR）. Western blotting and semi-quantitative immunohistochemistry were used to examine protein levels in human pancreatic cancer cell lines and pancreatic tissues, respectively, The role of αv integrin on gastrin-induced cell adhesion was examined using blocking anti-αv integrin monoclonal antibodies. Adherent cells were quantified by staining with crystal ***： Using a ＂cancer genes＂ array we identi- fied c^v integrin as a new gastrin target gene in human pancreatic cancer cells. A quantitative real-time PCR approach was used to confirm αv integrin gene expression. We also demonstrate that Src family kinases and the PI 3-kinase, two signalling pathways specifically activated by the CCK-2 receptor （CCK2R）, are involved in gastrin-mediated αv integrin expression. In contrast, inhibition of the ERK pathway was without any effect on αv integrin expression induced by gastrin. Our results also show that gastrin modulates cell adhesion via αv integrins. Indeed, in vitro adhesion assays performed on fibronectin show that gastrin significantly increases adhesion of pancreatic cancer cells. The use of blocking anti-αv integrin monoclonal antibodies completely reversed the increase in cell-substrate adhesion induced by gastrin. In addition, we showed in vivo that the targeted CCK2R expression in the pancreas of Elas-CCK2 mice, leads to the overexpression of αv integrin. This process may contribute to pancreatic turnout development observed in these transgenic ***： αv integrin is a new gastrin target in pancreatic cancer models and contributes to gastrin effects on cell adhesion.
