Blockade of TIM3 relieves immunosuppression through reducing regulatory T cells in head and neck cancer.
Liu, J.-F., et al. J Exp Clin Cancer Res. 2018 Mar 5;37(1):44. doi: 10.1186/s13046-018-0713-7. PMID: 29506555
The prophylactic administration of isotype IgG2a (clone 2A3) or anti-TIM3 (RMT3–23) (BioXCell, West Lebanon, NH) in mice was carried out by intraperitoneal injections (100 μg i.p.) for 3 days since day 12 and then once a week for the following weeks. ...In the transgenic HNSCC mouse model, blockade of TIM3 by the anti-TIM3 monoclonal antibody induced a reduction of CD4+CD25+Foxp3+ Tregs. ...Meanwhile, the population of TIM3+ Tregs was also decreased. ...Interestingly, the percent of TIM3+ Tregs was also down-regulated in the anti-TIM3 therapy group (Fig. 4e). ...It suggested that TIM3 may participate in the differentiation of Tregs, and that the blockade of TIM3 induced a decline in the number of Tregs.

Effect of TIM-3 Blockade on the Immunophenotype and Cytokine Profile of Murine Uterine NK Cells.
Tripathi, S., et al. PLoS One. 2015 Apr 21;10(4):e0123439. doi: 10.1371/journal.pone.0123439. PMID: 25897749
The treated group were injected i.p with anti TIM-3 mAb (clone RMT3-23, BioXCell) at doses 500μg, 250μg and 250μg at GD 6.5, 8.5 and 10.5 respectively. ...We determined if TIM-3 blockade significantly changes the cytokine and chemokine milieu at the FMI that affects the uNK cells. Allogeneically mated (CBA female x C57BL/6 male) female CBA mice treated with RMT3-23 (anti TIM-3) showed a decrease in the production of IL-6 (p = 0.0019), IL-15 (p = 0.0063) and IL-9 (p = 0.0128) in the placenta between G.D 10.5 and 12.5. ...The chemokine production in the placentae was also altered and a significant increase in the production of MIP1α (p = 0.0156), KC (murine equivalent of IL-8, p = 0.0276) and IP-10 (p = 0.0063) was observed in the placentae of RMT3-23 treated mice at G.D 10.5. ...We observed that TIM-3 is expressed on uNK cells and the number of uNK cells expressing TIM-3 increases steadily from GD 7.5 to 12.5, which is very similar to the expression of DBA on these cells. ...We used mAb RMT3-23 to block TIM-3 and observed the effect on the CD3 - CD122+ NK1.1 -DX5 - DBA+ cell population in the uteri at GD 7.5, 10.5 and 12.5.

A Threshold Level of Intratumor CD8+ T-cell PD1 Expression Dictates Therapeutic Response to Anti-PD1.

Purified anti-mouse PD1 mAb (RMP1-14), anti-mouse Tim3 (RMT3-23), anti-mouse PDL1 (10F.9G2), and control Ig (2A3) were purchased from BioXCell and used in the schedule and dose as indicated. ...We further confirmed our findings using a combination of anti-Tim3 and anti-PD1 mAbs in the CT26 tumor model, where a synergistic antitumor response of the combination was previously observed. ...The combination of anti-Tim3 and anti-PD1 mAbs induced a reduction in PD1+ intratumor CD8+ T cells consistent with the ability of anti-Tim3 to enhance an antitumor immune response toward CT26 via anti-PD1 therapy (Supplementary Fig. S5A and S5B). ...In contrast, consistent with no reduction in PD1+ T cells after the combination treatment of AT3 tumors (Supplementary Fig. S5C), anti-Tim3 and anti-PD1 mAb combination therapy was unable to suppress AT3 tumor growth (Supplementary Fig. S5D). ...We demonstrated that induction of intratumor Treg was, in part, a mechanism responsible for the development of anti-PD1–resistant tumors and PD1 hi CD8+ T cells.

Purified anti-mouse PD-1 mAb (RMP1-14), anti-mouse CTLA-4 mAb (UC10-4F10), anti-mouse Tim3 (RMT3-23) and control Ig (2A3) were purchased from BioXCell (West Lebanon) and used in the schedule and dose as indicated. ...Early treatment of B16F10-CD73 hi lung metastases by anti-CTLA-4, anti-PD-1, or anti-Tim3 mAb alone was relatively ineffective, compared with A 2ARi treatment alone over the same period. ...However, each of 3 checkpoint blockade mAbs, further enhanced the activity of A 2ARi when given coincidently in combination. ...on day 0 and 3 after tumor inoculation, mice were treated with intraperitoneal injections of vehicle, A 2ARi (SCH58261, 1 mg/kg), cIg (2A3, 250 μg), anti-CTLA-4 (UC10-4H10, 250 μg), anti-PD-1 (RMP1-14, 250 μg), anti-Tim3 (RMT3-23, 250 μg), or the combination as indicated. ...Total RNA was isolated from cancer cell lines and flow cytometry-sorted splenic lymphocytes by using RNAzol (Sigma-Aldrich) as per the manufacturer's instructions.

Combining regulatory T cell depletion and inhibitory receptor blockade improves reactivation of exhausted virus-specific CD8+ T cells and efficiently reduces chronic retroviral loads.
Dietze, K. K., et al. PLoS Pathog. 2013;9(12):e1003798. doi: 10.1371/journal.ppat.1003798. PMID: 24339778
To block the Tim-3 pathway, 100 µg rat anti-mouse Tim-3 Ab (RMT3-23; BioXCell) was administered intraperitoneally every other day for 4 times. ...Another group of animals was injected with monoclonal antibodies against PD-L1 and Tim-3 to block inhibitory receptor signaling on CD8+ T cells. ...A 4-fold expansion of CD43+ CD8+ T cells was also found in mice treated with α-PD-L1 and α-TIM-3 but it was significantly lower than in the group of Treg depleted mice. ...Treg depletion resulted in a higher expansion of the total population of activated CD8+ T cells compared to inhibitory receptor blockage, whereas it was the other way around for the expansion of the tetramer+ cells recognizing the immunodominant FV CD8+ T cell epitope. ...This was also the case for the subset of tetramer+ CD8+ T cells but for these cells recognizing the immunodominant FV epitope the treatment with α-PD-L1 and α-TIM-3 was more efficient for granzyme B induction than Treg depletion.
