The A-variant carbohydrate consists solely of this polyrhamnose structure which has been shown to contain alternating α1, 2-and α1, 3-linked rhamnose units. In agreement with results first published by Heidelberger and his coworkers (Estrada-Parraet al., 1963), the Group A carbohydrate has been shown to containN-acetylgulcosamine residues attached to the 3-position of the 1, 2-linked rhamnose units in this polyrhamnose structure. TheseN-acetylglucosamine residues impart group-specificity to the Group A carbohydrate. The Group C carbohydrate differs from the Group A carbohydrate by having 3-O-α-N-acetylgalactosaminosyl-N-acetylgalactosamine units attached to the 3-position of the polyrhamnose structure. TheseN-acetylgalactosamine disaccharides are capable of inhibiting the binding of Group C carbohydrate to anti-Group C sera and are cross-reactive with the Forssman antigen.</div>","PeriodicalId":13265,"journal":{"name":"Immunochemistry","volume":"15 10","pages":"Pages 755-760"},"PeriodicalIF":0.0,"publicationDate":"1978-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0161-5890(78)90105-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11306782","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}

LAF preparations were dialyzed 24-hr supernatants of partially purified rat macrophages and lacked mitogenic properties. Agents that increase cellular cAMP by different mechanisms (l-isoproterenol, prostaglandin E1, theophylline, and dibutyryl cAMP) were added before during, or after the period of optimal cell sensitivity to LAF. This period began approximately 16 hr after initiation of the cultures and lasted for about 8 hr. Addition of any of these reagents to the cultures during the first 8–12 hr of culture, i.e. before the period of cell sensitivity to LAF, resulted incomplete inhibition of both the PHA response and the LAF effect. Addition at 16 hr or later, though still inhibiting the PHA response markedly, gave insignificant inhibition of the LAF effect itself. Thus occurrence of a LAF effect requires effective lymphocyte triggering in order to reach the period of optimal cell sensitivity to LAF, a process which is sensitive to elevation of cellular cAMP, but the LAF effect on triggered cells is insensitive to cAMP. We conclude that the lymphocytes tested are heterogenous in their sensitivity both to LAF and to cAMP.</div>","PeriodicalId":13265,"journal":{"name":"Immunochemistry","volume":"15 10","pages":"Pages 807-811"},"PeriodicalIF":0.0,"publicationDate":"1978-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0161-5890(78)90114-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71848447","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}
