We report a new rationally-designed bispecific-antibody (BsAb), HX009, simultaneously targeting PD1 and CD47 to improve both the efficacy and safety over the respective single-targeting agents by grafting the extracellular domain of SIRPα onto the parental anti-PD1-monoclonal antibody, HX008. The IV single-dose toxicology study with a 14-day observation revealed a maximum tolerated dose of 150 mg/kg, while the repeated-dose (once weekly for 4 weeks, 5 doses in total) study showed a highest non-severely toxic dose (HNSTD) of 15 mg/kg. The desired preclinical PK and safety profiles, along with its antitumor activity, support HX009's candidacy for its clinical development.

Considering the need for advanced probes for noninvasive in vivo monitoring of T cell activation dynamics, we propose, that our hOX40-Nbs have a great potential as imaging probes for noninvasive and longitudinal in vivo diagnostics. Quantification of OX40+ T cells in TME or IME will provide crucial insights into the activation state of infiltrating T cells, offering a valuable biomarker for assessing immune responses, predicting treatment efficacy, and guiding personalized immunotherapy strategies in patients with cancer or IMIDs.

Treg/B cells have been applied for the treatment of some murine models of inflammatory diseases, including allergic asthma, inflammatory bowel disease, collagen-induced arthritis, gout, psoriasis and primary biliary cholangitis. This review summarizes the current knowledge of Treg/B cells.

These genes functionally enriched in promoting lymphocytes proliferation and may contribute to the enhanced persistence of CAR T cells. In conclusion, these results indicated the critical role of B cells in prolonging CAR T cells longevity and enhancing anti-tumor activity, which paves the way for the therapeutic exploitation of EphA2-CAR T cells against GBM in the future.

As the OX40 pathway is critical for expansion, differentiation, and survival of effector and memory T cells, its targeting might be a promising therapeutic approach to provide sustained inhibition of pathogenic T cells and associated inflammation and broad disease control. Antibodies against OX40 [rocatinlimab (AMG 451/KHK4083) and telazorlimab (GBR 830)] or OX40L [amlitelimab (KY1005)] have shown promising results in early-phase clinical studies of moderate-to-severe AD, highlighting the importance of OX40 signaling as a new therapeutic target in AD.

Further validation confirmed that IAV-OX40L enhanced the immune response mainly by activating Th1-dominant immune cells, releasing interferon-γ and interleukin-2. Taken together, our findings demonstrate the novel chimeric influenza OV could provide a potential therapeutic strategy for combating HCC and improve the effectiveness of virotherapy for cancer therapy.

While cereblon-modulating agents, such as pomalidomide and lenalidomide, have been found to improve the immune profile, the efficacy of their impact in combination with other treatments is yet unknown. The prognostic significance for the number of immune markers is only seen in the PVd arm and none of these immune markers exhibit prognostic values in the Vd arm. This study demonstrates the importance of the immunomodulatory effects and the therapeutic benefit of adding pomalidomide to Vd treatment.

Conclusions Consistent with the findings of our previous retrospective study (2), the ongoing prospective analysis of T-cell activation of diagnosis bone marrows of patients with AML suggests that testing TCR-mediated T-cell activation potential at diagnosis may help refine risk stratification of the heterogenous ELN intermediate risk group. AML immune suppression seems to be reversible in a minority of cases with the use of selected ICI inhibitors.

If further proven, our observations may be important in prognostication and prediction of response in melanoma. Furthermore, they may point to new IO combinations for further research and have therapeutic implications towards 'heating' up tumors.

Immunohistochemistry confirmed variable PD-1, CTLA-4, and OX40 expression in the CD4 T cell rosettes. This study introduced a new pathological approach to study the CHL TME, and provided deeper insight into CD4 T cells in CHL.

This work highlights OX40L expressed by tumor cells as a marker associated with sensitivity to PD-1 axis blockade alone for treatment nave NSCLC patients with high PD-L1 expressing. OX40L expression seems to be independent from PD-L1 expression at tumor compartment level. These data support the therapeutic modulation of OX40/OX40L axis combined with PD-1 axis inhibition particularly in this subgroup of patients.
