The sensitization was performed through the footpad. Eighteen days after sensitization, cellular immunity of the rabbits was tested with total homologous and heterologous antigens by direct and indirect migration inhibition tests using spleen macrophages. The bacteria were sonicated and centrifuged at 100,000 g for 1 h. The supernatant was used as the cytoplasmic antigen. Assayed by indirect migration, the migration index (MI) for homologous antigens was highly specific compared to heterologous antigens (MI of 0,60-0,65 compared to 0,79-0,96). The patterns obtained for rabbits sensitized with M. tuberculosis or M. kansasii when assayed by direct migration in the presence of homologous antigens (MI of 0,58 and 0,61, respectively) were similar. M. avium gave a distinct pattern. The results obtained indicate that crossed activity with heterologous antigens would be due to the presence of common components in the total antigens of the mycobacteria in question. On the other hand, the lower specificity of the direct test would result from the role played by humoral factors and antibodies, which might influence simultaneously migration of the target macrophages.</p>","PeriodicalId":75508,"journal":{"name":"Annales d'immunologie","volume":"133C 3","pages":"325-32"},"PeriodicalIF":0.0,"publicationDate":"1982-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17249063","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}

Eight overlapping cDNA fragments cover 4 700 out of the 5,100 +/- 200 nucleotides of the mRNA including its 3'-end. By partial DNA sequencing it has been found that the beta-chain is encoded in the 5'-half of the mRNA and must thus be located in the amino-terminal portion of the precursor polypeptide pro C3. From DNA sequences it is predicted that the amino-terminus of mouse C3-beta coincides in 12/15 residues with the known amino-acid sequence of guinea-pig C3 beta and in 9/10 residues with that of human C3 beta. A gene bank has been constructed from mouse DNA, from which four C3 genomic clones have been isolated. Two of them carry direct neighbouring fragments of 14- and 18-kilobase pairs of DNA, and contain one entire C3 gene (24-kilobase pairs). The 3'- and 5'-ends of the gene have been mapped. The DNA sequence at the 5'-end predicts that the initial translation product of the C3-mRNA is a prepro C3 molecule which carries at its amino-terminus a signal peptide of 24 amino-acids of typical composition. Human C3 genomic clones have been isolated and used to map the human C3 gene on a chromosome.</p>","PeriodicalId":75508,"journal":{"name":"Annales d'immunologie","volume":"133C 2","pages":"189-97"},"PeriodicalIF":0.0,"publicationDate":"1982-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18098752","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}

The basic mechanism of activation involves a limited proteolytic cleavage of C1r, with the generation of a proteolytic activity. Highly purified proenzymic C1r was obtained in high yield from human plasma by an indirect affinity chromatography step. Activation of isolated C1r in a fluid phase proceeded according to two distinct coexisting mechanisms: 1) an autocatalytic intradimer activation mediated by the pro-site of non-activated C1r; 2) an autocatalytic interdimer proteolysis triggered by nascent activated C1r formed in the course of the first reaction. DFP and C1-inhibitor did not have any effect on the first mechanism but were able to block the second mechanism.
