Differential antigen preservation during tissue autolysis
Human Pathology, 1991Immediate fixation or snap freezing of tissue is ordinarily done to maximize antigen preservation for immunocytochemistry; however, delay in tissue allocation or spontaneous lymph node infarction can render tissue suboptimal for immunostaining. To test the effects of tissue autolysis/necrosis on the preservation of various lymphoid, epithelial, and ...

DIFFERENTIAL SIGNALING BY LYMPHOCYTE ANTIGEN RECEPTORS
Annual Review of Immunology, 1997▪ Abstract Studies performed during the past several years make plain that ligand occupancy of antigen receptors need not necessarily provoke identical responses in all instances. For example, ligation of antigen receptors may stimulate a proliferative response, induce a state of unresponsiveness to subsequent stimulation (anergy), or induce apoptosis.

Serological identification of thymocyte differentiation antigens
Human Immunology, 1988We have examined subfractions of human thymocytes for the expression of novel differentiation antigens. Non-HLA alloantisera procured from multiparous women served as antibody probes. Thymocytes from five individuals were sequentially separated by discontinuous Percoll density gradient centrifugation and a peanut agglutinin (PNA) panning technique ...

Antigen-Initiated B Lymphocyte Differentiation
The Journal of Immunology, 1975Abstract Distinct sub-populations of B lymphocytes may be fractionated by passage through glass-bead columns, due to a temperature-independent adherence of certain cells. The relative adherence properties of AFC-progenitors from spleens of primed or unprimed CBA mice were compared with an adoptive immune assay employing as antigen the ...

Antigen Density on Differentiating Erythroid Cells
Nature New Biology, 1972THERE is a conflict of evidence about the development of erythrocyte antigens in the course of cell differentiation and maturation. Some reports suggest that antigens characteristic of mature erythrocytes can be demonstrated even on immature precursor cells1,2, but others3,4 suggest that red cell development is accompanied by significant changes of ...

Monocyte differentiation and antigen-presenting functions
Nature Reviews Immunology, 2017Monocytes develop in the bone marrow and represent the primary type of mononuclear phagocyte found in the blood. They were long thought of as a source for tissue macrophages, but recent studies indicate more complex roles for monocytes, both within the circulation and after their migration into tissues and lymphoid organs.

Differential Lysosomal Proteolysis in Antigen-Presenting Cells Determines Antigen Fate
Science, 2005Antigen-presenting cells (APCs) internalize antigens and present antigen-derived peptides to T cells. Although APCs have been thought to exhibit a well-developed capacity for lysosomal proteolysis, here we found that they can exhibit two distinct strategies upon antigen encounter.

[Differentiation antigens in keratinocytes].
Comptes rendus hebdomadaires des seances de l'Academie des sciences. Serie D: Sciences naturelles, 1977By means of indirect immunofluorescence with human sera it has been demonstrated that cytoplasmic components of the basal cell layer showed antigenic differences as compared to the upper cell layers. Moreover there were differences whether the cells were involved in a mucous, a parakeratinized or an orthokeratinized differentiation.

Characterization of human leukocyte differentiation antigens
Immunology Today, 1987What would impel 190 different laboratories to work together in the performance of more than 150 000 assays to characterize about 800 antibodies? Participants in the 3rd International Workshop on Human Leukocyte Differentiation Antigens generally shared the conviction that such cooperative effort has the potential to bring order out of the chaos of ...

[Human leukocyte differentiation antigens].
Presse medicale (Paris, France : 1983), 1984Over a small number of years many monoclonal antibodies directed against leucocytes have been produced. Their multiplicity and the various nomenclatures utilized may be disconcerting. As a result of the First International Workshop on Human Leucocyte Differentiation Antigens (Paris, 1982), a very clear correspondence between these different antibodies ...
