CD1a antibody | NA1/34-HLK
Image caption:
Endometrial CD4+cells express CCR5. (a) Scattered CD4+ cells were detected in the luminal and glandular epithelium as well as both stromal locations (lamina superficialis and lamina basalis). (b) Clusters of CD4+ cells were also detected just beneath the luminal epithelium and (c) adjacent to glandular epithelium. (d) A majority of the scattered CD4+ cells (red) co-expressed (yellow) CD3+ (green). (e) The lymphoid aggregate formations contained vast numbers of CD3+ cells (red) and occasional CD1a+ cells (green). (f) A positive co-localization (yellow) of CCR5+ cells (red) and CD4+ cells (green) was frequently observed both in the luminal epithelium and underlying stroma and (g) in the lymphoid aggregate formations. Arrowheads indicate example of double-positive staining; arrows indicate single-positive staining. Scale bars: a: 500 μm; b, c: 100 μm; d–f: 25 μm.

Image caption:
Distribution of antigen-presenting cell subsets in human endometrium. (a) CD1a+ cells were rare and mainly found within the luminal or glandular epithelium. (b) CD1a+ cells (green) co-expressed (yellow) CD11c+ (red), although not all CD11c+ cells expressed CD1a. (c) The CD1a+ cells (green) also expressed CD4 (red). (d) CD11c+ and (e) CD68+ cells were present in much higher frequencies in both the epithelium and stroma and clusters of both (f) CD11c+ and (g) CD68+ cells were present in the lamina basalis adjacent to glandular epithelium (marked area: 7.1×104 μm2 and 8.1×104 μm2, respectively). (h) CD123+ cells were solely present in the stroma as scattered cells and in streak formations. (i) Some but not all CD123+ (red) cells co-localized (yellow) with BDCA-2 (green). BDCA-2+ (green) neither co-localized with (j) CD11c+ (red) nor (k) CD68+ (red) cells, although they were occasionally detected in close proximity to each other. Arrowheads indicate example of positive staining. Scale bars: a: 500 μm; b, c, j, k: 25 μm; d–i: 100 μm.

Image caption:
CLR expression on various DC subsets present in the endometrium. (a) Langerin positive cells were mainly detected within the luminal and glandular epithelium. Positive co-localization (yellow) was detected with Langerin+ cells (green) and (b) CD1a (red) and (c) CD11c (red). (d) Double-positive cells (yellow) expressing Langerin+ (green) and CD4+ (red) cells were also detected within CD4+ lymphoid aggregates. (e) DC-SIGN and (f) MR were detected in the lamina superficialis, just beneath the luminal epithelium (I: minimum distance of cell body to endometrial lumen: 49 µm and 40 µm, respectively). Both (g) DC-SIGN (green) and (h) MR(green) were co-expressed (yellow) on CD68+ cells (red) as well as (i and j, respectively) CD11c+ cells (red). Neither (k) DC-SIGN (red) nor (l) MR (red) were expressed on CD1a+ (green) cells. Scale bars: a: 500 μm; b–d: 25 µm; e–l: 100 µm.

| Mouse anti Human CD1a antibody, clone NA1/34-HLK recognizes the human CD1a cell surface glycoprotein, a ~49 kDa single pass type 1 transmembrane glycoprotein containing a single Ig-like domain, expressed in association with beta 2 microglobulin. CD1a is expressed strongly by cortical thymocytes, and also by Langerhans cells and interdigitating cells. CD1a is involved in the presentation of lipids and glycolipids to NK cells ( |
