Purpose: We designed a CD19-targeted chimeric antigen receptor (CAR) comprising a calibrated signaling module, termed 1XX, that differs from that of conventional CD28/CD3ζ and 4-1BB/CD3ζ CARs. Preclinical data demonstrated that 1XX CARs generated potent effector function without undermining T-cell persistence. We hypothesized that 1XX CAR T cells may be effective at low doses and elicit minimal toxicities.

METTL3 is the RNA methyltransferase predominantly responsible for the addition of N-methyladenosine (mA), the most abundant modification to mRNA. The prevalence of mA and the activity and expression of METTL3 have been linked to the appearance and progression of acute myeloid leukemia (AML), thereby making METTL3 an attractive target for cancer therapeutics. We report herein the discovery and optimization of small-molecule inhibitors of METTL3, culminating in the selection of as an proof-of-concept compound.

HIV-1 envelope broadly neutralizing antibodies represent a promising component of HIV-1 cure strategies. To evaluate the therapeutic efficacy of combination monoclonal antibodies (mAbs) in a rigorous nonhuman primate model, we tested different combinations of simian immunodeficiency virus (SIV) neutralizing mAbs in SIVmac251-infected rhesus macaques. Antiretroviral therapy-suppressed animals received anti-SIV mAbs targeting multiple Env epitopes spanning analytical treatment interruption (ATI) in 3 groups (n = 7 each): i) no mAb; ii) 4-mAb combination; and iii) 2-mAb combination.

Discoidin domain receptors (DDR) are categorized under tyrosine kinase receptors (RTKs) and play a crucial role in various etiological conditions such as cancer, fibrosis, atherosclerosis, osteoarthritis, and inflammatory diseases. The structural domain rearrangement of DDR1 and DDR2 involved six domains of interest namely N-terminal DS, DS-like, intracellular juxtamembrane, transmembrane juxtamembrane, extracellular juxtamembrane intracellular kinase domain, and the tail portion contains small C-tail linkage. DDR has not been explored to a wide extent to be declared as a prime target for any particular pathological condition.

Adenosine-mediated activation of AR drives immunosuppressive signaling in high-adenosine tumor microenvironments (TMEs), impeding anticancer immunity. Targeting AR with negative allosteric modulators (NAMs) is a promising approach for cancer immunotherapy: unlike the orthosteric antagonists currently in use, which face competitive and off-target limitations, NAMs leverage a noncompetitive, saturable mechanism that enhances receptor selectivity. The development of a novel series of AR NAMs demonstrates potent activity within high-adenosine TMEs, underscoring a significant translational potential in oncology.
