New insights to the functional role of the T cell-Antigen Presenting Cell immunological synapse
(Sociedad de Biología de Chile, 2002)
Distinct localization of T cell Agrin during antigen presentation - evidence for the expression of Agrin receptor(s) in antigen-presenting cells
Agrin is over-expressed by activated and autoimmune T cells, and synergizes with the T cell receptor (TCR) to augment cell activation. In the present study, we show that Agrin accumulates to distinct areas of the plasma ...
The proliferating cell nuclear antigen index in breast carcinomas does not correlate with mitotic index and estrogen receptor immunoreactivity
(Gustav Fischer Verlag, 1994-09-01)
To investigate the expression of a marker of cell proliferation (PCNA/Cyclin) and its putative relationship with histological grading, mitotic index and estrogen receptor immunoreactivity, we studied twenty-seven cases of ...
T CELL RECEPTOR BINDING KINETICS REQUIRED FOR T CELL ACTIVATION DEPEND ON THE DENSITY OF COGNATE LIGAND ON THE ANTIGEN-PRESENTING CELL
(NATIONAL ACADEMY OF SCIENCES, 2005)
The non-palindromic adaptor-PCR method for the identification of the T-cell receptor genes of an interferon-gamma-secreting T-cell hybridomaspecific for trans-sialidase, an immunodominant Trypanosoma cruzi antigen
(Associação Brasileira de Divulgação Científica, 2006-03-01)
Cloning of the T-cell receptor genes is a critical step when generating T-cell receptor transgenic mice. Because T-cell receptor molecules are clonotypical, isolation of their genes requires reverse transcriptase-assisted ...
