Shortly after intranasal infection of guinea pigs with Mycoplasma pneumoniae, the titers of the complement components increased significantly in bronchial secretions by the folllowing amounts, compared with the titer of a control group: C1, about 2-fold; C2, 1.6-fold; C3, 17-fold; and C4, 942-fold. Histopathological signs of inflammation were not apparent at this time. At 2 weeks after infectio...
Hepatocytes which had been isolated from the livers of Charles River rats were cultured in vitro. The cells were shown to synthesize albumin and the complement components C4, C2, C3 and B. Pulse-label studies with [35S]methionine showed that C4 and C3 were synthesized as single polypeptide chains. Pro-C4 did not appear to be converted into the plasma form of C4 intracellularly, whereas cell lys...
1. At a temperature of 1 degrees C., C'2, C'4, and C'1 combine with sensitized sheep erythrocytes, while C'3 does not combine. 2. C'1, although combining with sensitized cells in the absence of C'4, is hemolytically inert unless C'4 combines previous to, or simultaneously with it. 3. C'4 does not combine in the absence of C'1. 4. Although C'3 is not fixed by antibody-sheep cell aggregates, it i...
The discovery of giant viruses blurred the sharp division between viruses and cellular life. Giant virus genomes encode proteins considered as signatures of cellular organisms, particularly translation system components, prompting hypotheses that these viruses derived from a fourth domain of cellular life. Here we report the discovery of a group of giant viruses (Klosneuviruses) in metagenomic ...
