Morphologic heterogeneity as well as a wide variation in the content of nonspecific esterase, acid phosphatase (AP), and myeloperoxidase (MP) were observed with standard cytochemical stains. This heterogeneity was evident within the same sample as well as between different individuals. Phagocytic activity was also highly variable. In only 3 cases out of 85 samples screened could human peritoneal macrophages be characterized as resident (peroxidase negative, acid phosphatase negative) by the criteria used in rodent systems, thus indicating that female peritoneal macrophages are continuously responding to stimuli/irritation. A newly developed flow cytofluorometric method was used to quantitatively document the macrophage heterogeneity in enzyme expression and phagocytic activity. Population distributions derived from single-cell analysis of various enzyme activities and phagocytic levels further emphasized the spread in expression of these parameters both within the individual peritoneal samples as well as between donors. Simultaneous determination of two markers such as leucine aminopeptidase (LAP) and zymosan ingestion indicated that the association between these features varied markedly between individuals. It is hoped that the use of this multiparameter flow cytometric technique on in vitro differentiating blood monocytes, subjected to different stimuli, will give us a better understanding not only of the development of monocytes to macrophages but also of the sources of heterogeneity in normal human resident macrophages.</p>","PeriodicalId":17481,"journal":{"name":"Journal of the Reticuloendothelial Society","volume":"33 2","pages":"127-38"},"PeriodicalIF":0.0,"publicationDate":"1983-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17250971","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}

Infection of mineral oil-elicited peritoneal M phi cultures with either the virulent (Moscow) or attenuated (Hampstead) strain of ectromelia virus led to productive infections. The kinetics of virus synthesis was similar to those seen following infection of murine fibroblasts. In contrast, peritoneal M phi s activated by intraperitoneal injection of Corynebacterium parvum vaccine were found to be totally refractory to infection by the attenuated strain and significantly more resistant to the virulent strain of ectromelia virus. Administration of C. parvum doses as small as 7 micrograms were sufficient to induce antiviral activity. M phi resistance became maximal at 5-9 days after C. parvum administration; however, M phi resistance was unstable during in vitro culture. Decay of antiviral activity was detected within the first 24 hr of culture and complete virus susceptibility returned after 5 days in culture. Peritoneal exudate cells (PEC) from C. parvum-immunized mice could induce resistance in susceptible M phi cultures during overnight cocultivation. In addition, cell-free culture supernatants from C. parvum-immune PEC could also induce resistance in susceptible M phi cultures, suggesting that a soluble factor, induced by C. parvum immunization and possessing interferon activity, may account for the intrinsic resistance to ectromelia virus by activated M phi s.</p>","PeriodicalId":17481,"journal":{"name":"Journal of the Reticuloendothelial Society","volume":"33 1","pages":"35-46"},"PeriodicalIF":0.0,"publicationDate":"1983-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17362034","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}

Purification of plasma-opsonic fibronectin by affinity chromatography with gelatin-Sepharose revealed that although in vitro hepatic Kupffer cell phagocytosis was absolutely dependent upon the presence of fibronectin, the purified fibronectin evaluated in concentrations similar to that found in plasma (350-450 micrograms/ml) supported phagocytosis at a level two- to threefold less than that observed in whole plasma. In contrast, the combination of purified fibronectin with small aliquots of opsonically inactive fibronectin-free plasma restored normal opsonic activity as assessed by liver slice bioassay and enhanced fibronectin-mediated attachment of gelatinized particulate to isolated Kupffer cells in vitro. Evidence is presented in this study that there exists in plasma a macromolecular species that amplifies the opsonic activity of fibronectin in a dose-related manner. This amplification or cofactor activity is nondialysable and has a molecular weight greater than 12,000. Inactivation of the amplification activity present in affinity-absorbed plasma can be achieved by heating the fibronectin-free plasma at 60 degrees C for 20 min, supporting the hypothesis that the cofactor is a protein. The amplification response is dose related, suggesting that the mechanism of its action is stoichiometric rather than catalytic. Evidence is presented that partial purification of the cofactor can be achieved by (NH4)2SO4 precipitation at 4 degrees C. Purification of this cofactor will provide an opportunity to evaluate its role in the altered opsonic states known to exist after trauma, burn, and sepsis.</p>","PeriodicalId":17481,"journal":{"name":"Journal of the Reticuloendothelial Society","volume":"33 1","pages":"21-33"},"PeriodicalIF":0.0,"publicationDate":"1983-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17886167","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}
