CD1a expression in PEComas

Pathology International, 2008
According to the World Health Organization classification, neoplasms with perivascular epithelioid cell differentiation (PEComas) are mesenchymal tumors composed of histologically and immunohistochemically distinctive PEC. Generally, nearly all PEComas have immunoreactivity for both melanocytic (HMB‐45 and/or melan A) and smooth muscle (actin (SMA) and/

CD1a and antitumour immune response

Immunology Letters, 2004
Primary immune response is based on the capacity of local professional antigen-presenting cells (whose prototype is represented by dendritic cells, DCs) to take up and present antigens to selected clones of T cells, but also to non-specific effector cells such as macrophages or natural killer cells.

CD1a-Positive Cells in Odontogenic Cysts

Journal of Endodontics, 2002
Langerhans cells (LC) are bone marrow-derived cells that have a CD1a-positive immunophenotype and are an important portion of the cell-mediated immune response. The aim of this study was an immunohistochemical evaluation of CD1a positive cells in different types of oral cysts.

CD1a+ and CD1a- Accessory Cells from Human Bronchoalveolar Lavage Differ in Allostimulatory Potential and Cytokine Production

American Journal of Respiratory Cell and Molecular Biology, 1996
Abstract Recently, we described the isolation through fluorescent-activated cell sorting (FACS) of low autofluorescent (LAF) cells from human bronchoalveolar lavage (BAL). These LAF cells displayed an immunophenotype comparable with that of dendritic cells (DC), and showed a high potency to stimulate naive T cells.
