The significance of this expression is unknown since the expression of these antigens by benign T cells has not been fully investigated. In this study the kinetics, temporal relation and hierarchy of expression of these eight cell surface antigens by purified normal peripheral blood T cells following activation with phytohemagglutinin (PHA) were investigated using one- and two-color flow cytometry. All eight antigens were expressed in a hierarchical manner following activation of normal peripheral blood T cells with PHA. The sequence of antigen expression and the initial time point of this expression was: CD38, < 24 h; CD71, CD25, 24 h; EMA, HLA-DR, CD15, 48-72 h; CD30, 72 h; and CD11c, 96-120 h. The maximum percentage of T cells expressing each antigen and the time point of maximum expression was: CD38 96% at 14 and 17 days; CD71 88%, CD25 94%, EMA 55%, and CD30 31% at 96 h; CD15 56% at 120 h; HLA-DR 30% at 168 h; and CD11c 42% at 240 h. The expression of these 8 antigens clustered into six distinct immunophenotypic constellations: Group I: None; Group II: CD38 with CD71 and/or CD25; Group III: CD38, CD71, CD25 with HLA-DR, CD15 and/or EMA; Group IV: CD38, CD71, CD25, EMA, HLA-DR with CD15, CD30 and/or CD11c; Group V: CD38, CD25, CD11c with CD71, EMA and/or HLA-DR; Group VI: CD38 with CD25 and/or CD11c. Finally, EMA and CD11c were preferentially expressed by CD4 and CD8 T cells, respectively. In summary, these results demonstrate that all eight antigens (1) are associated with T-cell activation, (2) are expressed in a hierarchical manner following activation, and (3) that this expression clusters into distinct immunophenotypic constellations.</p>","PeriodicalId":77160,"journal":{"name":"Hematologic pathology","volume":"6 4","pages":"193-202"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12536052","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}

This report discusses membrane-associated erythrocyte TGase activity which can crosslink substrates at micromolar calcium concentrations in the presence of calmodulin (CaM). This TGase activity coisolates with a 1 M NaCl extraction of cytoskeletal components and is purified by CaM affinity chromatography.

Sodium dodecyl sulfate polyacrylamide gel electrophoresis of this eluate demonstrates two bands of 68,000 and 72,000 daltons. TGase crosslinking of fibronectin, fibrinogen, and membrane cytoskeletal substrates was associated with substrate degradation and could be inhibited competitively by putrescine.

In most cases they are due to iron deficiency, but in some geographical areas other diagnoses, such as that of beta-thalassemia trait, must be considered. In some cases, the hematological data presented by the automated hemogram may be very similar in both entities, showing moderate anemia, microcytosis, and increased red blood cells. From a practical point of view, it may be important to make an \"at-first sight\" diagnosis using simple parameters that may readily be obtained from the hemogram or from the laboratory. We have assessed the usefulness of RDW (red cell distribution width), of the England-Fraser index and of free erythrocyte protoporphyrin determination in predicting iron deficiency anemia or beta-thalassemia trait.
