are control T cells (grey columns) while those derived from mice mice vaccinated with B16alpha Gal
(melanoma cells with sugar) are α gal T cells (black columns).
black shows sugar positive melenoma cells

HSP. cells give up when under stress FACS analysis was done on gated CD8 cells (control T cells and α gal T cells) incubated in vitro with either colon cancer
galactosyl negative targets (CA320M) or B16 null (galactosyl negative) melanoma cell targets. Intracellular TNF was measured
by permeabilizing CD8 cells so antibody could enter the CD8 cells and bind to TNF. CD3 was measured by antibody binding to
cell surface portions of CD3. cross presentation. class 1 presentation. proteozome 9-10 amino peptides. tap 1 and tap 2 that requires ATP. Overview of Class I presentation Overview of Class II presentation
