The purpose of this study was to investigate the effect of LPS on synaptic transmission at the neuromuscular junction (NMJ) of a model amphibian preparation. The cutaneous pectoris muscle of Lithobates pipiens was dissected and maintained in a physiological saline to acutely expose the preparation to LPS from Serratia marcescens. The evoked excitatory junction potentials (EJPs) completely diminished after 10 min (n = 6, p<0.05 paired t-test). These EJPs were able to be partially recovered after removal of LPS. The frequency and amplitude of the spontaneous miniature excitatory junction potentials (mEJPs) did not change with LPS exposure (n = 6, p>0.05 paired t-test). These findings suggest that LPS acts in frogs by inhibiting the activity of the voltage-gated Ca2+ channels in presynaptic motor neurons and not by blocking the acetylcholine receptors on the skeletal muscle fibers. These findings imply the acute action of LPS in mammals is presynaptic at the NMJs and can suppress synaptic transmission independent of initiating a systemic immune response.","PeriodicalId":166162,"journal":{"name":"International Journal of Zoological Research","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124292243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Generally ectothermic animals cannot generate heat to maintain their body temperature but they can still survive in various temperature zones. Various organisms have been analyzed anatomically and physiologically in the attempt to understand the underlying mechanisms of this temperature adaptation. A few of the changes in the metabolic and molecular function of proteins are discussed. The potential of how hormonal modulation of cardiac and nervous systems which influences responses during exposure cold exposure is also addressed. The focus of this review is on the effect of cold exposure on synaptic transmission and cardiac function in crustaceans and insects.","PeriodicalId":166162,"journal":{"name":"International Journal of Zoological Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130942738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
