They do not usually express CD5, CD23, CD43
, or Bcl-1, and T-cell markers are absent (6).
This structure is composed of concentric rings each containing a peculiar mix of molecules: c-SMAC (central-SMAC) composed of 0 isoform of protein kinase C, CD2, CD4, CD8, CD28, Lck, and Fyn; p-SMAC (peripheral-SMAC) composed of the lymphocyte function-associated antigen-1 (LFA-1), CTLA-4, and the cytoskeletal protein talin; d-SMAC (distal-SMAC) composed of CD43
and CD45 molecules.
These immunohistochemical studies included reagents specific for CD3, CD11c, CD20, CD33, CD43
, CD68, CD117, CD163, lysozyme, and myeloperoxidase.
The primary antibodies used for immunocytochemistry were as follows: CD2 (clone AB75, NeoMarkers); CD3 (clone SP7, NeoMarkers); CD4 (clone 4B12, DAKO); CD5 (clone CD5/54/F6, DAKO); CD7 (clone 272, NeoMarkers); CD8 (clone C8/144B, DAKO); CD19 (clone LE-CD19, DAKO); CD20 (clone L26, NeoMarkers); CD30 (clone Ber-H2, DAKO); CD43
(clone DF-T1, NeoMarkers); CD45 (Clone 2B11 + PD7/26, DAKO); CD138 (clone M115, DAKO); ALK-1 (clone ALKO1, NeoMarkers); EMA (clone E29, DAKO); EBV/LMP (clone CS.
Immunohistochemically, the cells were positive for CD3 (cytoplasmic stain), CD56 (figure, B), CD43
, CD30, TIA-1, and granzyme B.

2001) reported that mast cells could phagocytize diverse particles, take up antigens, and express a number of receptors, particularly MHC class I and II antigens, ICAM-1 and -3, CD43
, CD80, CD86 and CD40L, and allow them to interact with T and B lymphocytes.
By immunohistochemistry on both blocks, the majority of cells in the expanded mantle zones or marginal zones were positive for CD 20 and BCL-2, negative for CD5, cyclin D1, CD10, CD3 and CD43
Although the number of antibodies used for immunophenotyping varied from case to case, all cases included immunoglobulin light and heavy chains, as well as CD3, CD4, CD5, CD8, CD10, CD11c, CD19, CD20, CD23, CD43
, and FMC7.
terminal deoxy-nudeotidyl transferase, c-Kit, CD25, CD19, CD43
, CD69, and IL-7R), has often been used to examine lymphoid tissues from prenates and neonates.
