WebFeb 15, 2024 · Acute lymphoblastic leukemia (ALL) represents the most common pediatric cancer. Most patients (85%) develop B-cell ALL; however, T-cell ALL tends to be more aggressive. We have previously identified 2B4 (SLAMF4), CS1 (SLAMF7) and LLT1 (CLEC2D) that can activate or inhibit NK cells upon the interaction with their ligands. In this study, … WebCD3 is expressed on all peripheral T lymphocytes. CD2, which was the cell surface receptor initially identified by E-rosette formation, is also present on most T lymphocytes. Normal peripheral blood T lymphocytes express either CD4 or CD8; thus, peripheral blood T lymphocytes can be characterized as CD3+, CD4+ or CD3+, CD8+ leucocytes.
