| T Cell Type | TCR Type | Recognized Antigens | MHC Molecule Type |
|---|---|---|---|
| Classical helper and cytotoxic T cells | αβ TCRs | Peptides | Class I or Class II MHC |
| Semi-invariant T cells | αβ TCRs (limited diversity) | Lipid antigens or small organic molecules | Nonclassical MHC |
its antigen recognition is fundamentally different than that of αβ T cells
其抗原识别与αβT细胞有着根本的不同
Later work showed that most or all γδ T cells recognize antigens directly, like antibodies, and that the MHC molecules are not an obligatory component of γδ T cell antigens.
