Invited review Giardia duodenalis: Inter-strain variability of proteins, antigens, proteases, isoenzymes and nucleic acids
Giardia duodenalis isolates from asymptomatic or symptomatic patients and from animals present similarities and differences in the protein composition, antigenic profile, pattern of proteases and isoenzymes, as well as in ...
Peripheral giant cell granuloma. An immunohistochemical and ultrastructural study.
OBJECTIVE: To study the nature of multinucleated and mononuclear cells from peripheral giant cell granuloma (PGCG). MATERIALS AND METHODS: Formalin-fixed, paraffin-embedded sections of 40 cases of PGCG were immunohistochemically ...
New insights to the functional role of the T cell-Antigen Presenting Cell immunological synapse

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 ...
Characterization of a Testis Specific Antigen in the Mouse
Summary: The partial characterization of a mouse hydrosoluble testis specific protein by crossed immunoelectrophoresis, ion‐exchange chromatography and SDS‐Page was made. This protein presented a low electrophoretic motility ...
Antigen presentation unfolded: identifying convergence points between the UPR and antigen presentation pathways
The unfolded protein response (UPR) is an adaptive response meant to restore endoplasmic reticulum homeostasis in conditions of ER stress that subvert the folding capacity of the cell. Over the past few years, it has become ...
MHC I presentation of Toxoplasma gondii immunodominant antigen does not require Sec22b and is regulated by antigen orientation at the vacuole membrane
(Wiley VCH Verlag, 2017-07)
The intracellular Toxoplasma gondii parasite replicates within a parasitophorous vacuole (PV). T. gondii secretes proteins that remain soluble in the PV space, are inserted into PV membranes or are exported beyond the PV ...
Immunohistochemical Characterization of Human Synovial Bursa Cells by Light and Transmission Electron Microscopy: Where do These Cells Come From?
