Article Title: Linked CD4 + /CD8 + T cell neoantigen vaccination overcomes immune checkpoint blockade resistance and enables tumor regression
Article Snippet: .. In select experiments, CD4+ T cells were purified using the EasySep Mouse CD4 Positive Selection kit II, and CD8+ T cells were negatively selected from the supernatant fraction using the EasySep Mouse CD8+ T cell Isolation kit (STEMCELL Technologies). .. Bulk leukocytes or purified T cells were placed in co-culture with day 7 rIL-4 and rGM-CSF (Tonbo Biosciences, San Diego, CA) matured bone marrow-derived dendritic cells (BMDC) at a 10:1 ratio (2×105:2×104 mononuclear cells:BMDCs) in triplicate to multiscreen-IP filter 96-well plates (MilliporeSigma, St. Louis, MO) coated overnight with 2 μg/mL anti-IFN-γ (clone AN18; #3321-3-1000) capture antibody (MabTech, Cincinnati, OH).

Article Title: 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
Article Snippet: .. EasySep Mouse CD4 Positive Selection Kit II (StemCell Technologies, Vancouver, BC, Canada, CAT# 18952) and EasySep Mouse CD8a Positive Selection Kit II (StemCell Technologies, Vancouver, BC, Canada, CAT# 18753) were used to separate CD4 + and CD8 + T cells from splenocytes. ..

Article Title: Aberrant T follicular helper cells generated by T H 17 cell plasticity in the gut promote extraintestinal autoimmunity.
Article Snippet: Much remains unknown regarding T follicular helper 17 (TFH17) cells commonly found in autoimmune patients.. We previously showed that (and here ask why) egress of gut segmented filamentous bacteria (SFB)-induced TFH cells from Peyer’s patches (PP) to systemic sites promotes arthritis.. We found splenic TFH17 cells are gut derived.

Article Title: IFNγ at the early stage induced after cryo-thermal therapy maintains CD4 + Th1-prone differentiation, leading to long-term antitumor immunity
Article Snippet: .. EasySep Mouse CD4 Positive Selection Kit II (Cat# 18952, StemCell Technologies, Vancouver, BC, Canada) were used for CD4 + T cell isolation. .. For MDSCs isolation, GR-1 positive cells were labeled with APC by monoclone antibody (Biolegend, San Diego CA), and subsequently selected with the EasySep Mouse APC Positive Selection Kit II (Cat# 17667, StemCell Technologies) following the given instructions from the manufacturer.
