  • Live HeLa cells transfected with human TIM-3 were immunostained with CoraLite® Plus 555 conjugated-TIM3 VHH (CL555-tmt,1:1000, yellow). After formaldehyde fixation, triton permeabilization and blocking with BSA, intracellular pool of TIM-3 was immunostained with CoraLite® Plus 647 conjugated-TIM3 VHH (CL647-tmt, 1:1000, magenta). Cell nuclei were stained with DAPI (cyan). Epifluorescence images were acquired with a 20x objective and post-processed.

Background TIM3, also known as HAVCR2, is a member of the recently discovered T cell Ig and mucin domain-containing molecule superfamily. TIM3 is a negative regulatory molecule that is important for T cell tolerance and has a crucial role in autoimmunity and T cell exhaustion during chronic viral infection (PMID: 23180819). TIM3 is expressed by T-helper type 1 (Th1) cells, macrophage, monocyte, dendritic cells, CD8+ T cell and other lymphocyte subsets. Galectin-9 is a ligand for TIM3. TIM3-galectin-9 pathway negatively regulates T helper type 1 immunity (PMID: 16286920). TIM3 is a 280-aa membrane protein with a calculated molecular weight of 33 kDa, the higher molecular weights between 50 and 70 kDa detected by this monoclonal antibody probably represent glycosylated TIM3 (PMID: 20107545; 17069754; 11725301).
