T cell activation via presentation of SARS-CoV‑2 antigens by artificial antigen presenting cells (aAPC-mediated T cell activation (SARS-CoV-2))
- Target
- aAPC-mediated T cell activation (SARS-CoV-2)
- Molecular classification
- Antigen Presentation, T Cell Receptor Signaling, Artificial Antigen Presenting Cell, MHC-Peptide Complex
01
Overview
This target refers to the activation of T cells through the presentation of SARS-CoV-2 antigens by artificial antigen-presenting cells (aAPCs). aAPCs are engineered to express MHC molecules loaded with viral peptides, mimicking natural antigen presentation and allowing for controlled T cell stimulation, expansion, and functional analysis. This approach is utilized in research and potential immunotherapies to study and enhance immune responses against SARS-CoV-2, offering opportunities for vaccine development, immune monitoring, and adoptive T cell therapy.

02
Mechanism of action
Activation of T cells (CD4+ and CD8+) through the presentation of SARS-CoV-2 peptide antigens on MHC molecules (I and II) by artificial antigen-presenting cells (aAPCs). This interaction leads to T cell receptor (TCR) engagement, co-stimulation, proliferation, and effector function development.
