Precision TCR Engineering for Targeted T Cell Therapies

The TCR complex is composed of several subunits, including the TCR alpha (α) and TCR beta (β) chains, as well as the CD3 complex, which consists of CD3 epsilon (ε), CD3 gamma (γ), CD3 delta (δ), and CD3 zeta (ζ) subunits. These components work synergistically to ensure T cells can accurately recognize antigens and initiate appropriate immune responses, playing a vital role in maintaining immune surveillance and responding to pathogens and abnormal cells.

Here's a detailed overview of these subunits and their functions:

*TCR Subunit*	*Structure*	*Function*	*Key Features*
TCR Alpha (α)	Variable (V) and Constant (C) regions	Recognizes peptide-MHC complexes	Generated through V(D)J recombination for antigen diversity
TCR Beta (β)	Variable (V) and Constant (C) regions	Recognizes peptide-MHC complexes	Generated through V(D)J recombination for antigen diversity
CD3 Epsilon (ε)	Single-pass transmembrane protein	TCR assembly, expression, and signal transduction	Contains ITAMs for phosphorylation and signal transduction
CD3 Gamma (γ)	Single-pass transmembrane protein	Stabilizes TCR complex, signal transduction	Contains ITAMs for phosphorylation and signal transduction
CD3 Delta (δ)	Single-pass transmembrane protein	TCR assembly and expression, signal transduction	Contains ITAMs for phosphorylation and signal transduction
CD3 Zeta (ζ)	Homodimer, long cytoplasmic tail	Major role in signal transduction	Multiple ITAMs for initiating intracellular signaling cascades
