LFA-1/ICAM-1 Interactions Between CD8⁺ and CD4⁺ T Cells Promote CD4⁺ Th1-Dominant Differentiation and CD8⁺ T Cell Cytotoxicity for Strong Antitumor Immunity After Cryo-Thermal Therapy.

ABSTRACT: CD4⁺ T cells have been well-regarded as "helper" cells in activating the cytotoxicity of CD8⁺ T cells for effective tumor eradication, while few studies have focused on whether CD8⁺ T cells regulate CD4⁺ T cells. Our previous studies provided evidence for an interaction between CD4⁺ and CD8⁺ T cells after cryo-thermal therapy, but the mechanism remains unclear, especially pertaining to how CD8⁺ T cells promote the Th1 differentiation of CD4⁺ T cells. This study revealed that activated CD4⁺ and CD8⁺ T cells are critical for CTT-induced antitumor immunity, and the interaction between activated T cells is enhanced. The reciprocal regulation of activated CD8⁺ and CD4^+</
