Both B2M (Beta-2-Microglobulin) and CIITA (Class II Transactivator) have been genetically removed from THP-1 cells using CRISPR/Cas9 genome editing.
Mycoplasma testing: The cell line has been screened to confirm the absence of Mycoplasma species.
Host Species: human
Supplied as Each vial contains 2 x 106 cells in 1 ml of cell freezing medium (Biohippo, #79796)
Background
Beta-2-Microglobulin is a required component of Major Histocompatibility Complex (MHC) class I molecules, which present peptide fragments from within a cell to cytotoxic T cells as part of the adaptive immune system. B2M plays an essential role both in governing MHC class I molecule stability and in promoting antigen binding and presenting the antigen to CD3/TCR complex of CD8+ T cells.CIITA (Class II Transactivator, also known as Class II Major Histocompatibility Complex Transactivator) acts as a coactivator for MHC class II-specific gene expression. IFN-Ƴ induces CIITA gene expression via the JAK1 and STAT1 pathways. Defects in CIITA have been implicated in Bare Lymphocyte Syndrome (BLS), which is characterized by the absence of MHC class II transcription and severe immunodeficiencies.
Application
Study the consequences of deficient MHC class I and II.Study T cell activation, antigen presentation, and immune responses.Useful for the development of improved universal CAR-T or other effector cells.
Host Cell
THP-1, monocyte, suspension
