Immunosuppressive myeloid cells are important in a variety of physiological and pathological contexts, including tumor development, but how hormones might regulate their activity is unclear. Secretogranins, a family of secretory proteins in endocrine and neuronal cells, are proposed to function as prohormones or hormones, but their specific receptors are unknown. Here we show that secretogranin 2 (SCG2), a granin family member, functionally interacts with leukocyte immunoglobulin-like receptor B4 (LILRB4) on monocytic cells.

Immunosuppressive myeloid cells are critical obstacles to T cell-centered immune checkpoint blockade therapies, which have been successful in treating a fraction of patients with cancer. How tumor cells interact with myeloid cells to regulate immune responses and tumor development is unclear. In this study, we report that certain membrane tyrosine kinase Eph receptors, including EphA7 and EphB1, specifically bind the immune inhibitory receptors leukocyte Ig-like receptor family B 5 (LILRB5) and LILRB2.

Advancements in emergency medicine and critical care have significantly improved survival rates for patients with severe acquired brain injuries(sABI), subsequently increasing the prevalence of disorders of consciousness (DoC) such as Unresponsive Wakefulness Syndrome (UWS) and Minimally Conscious State (MCS). However, the assessment of conscious states relies on the observation of behavioral responses, the interpretation of which may vary from evaluator to evaluator, as well as the high rate of misdiagnosis, which together pose significant challenges for clinical diagnosis. The study investigates the utility of transcutaneous auricular vagus nerve stimulation (taVNS) in modulating autonomic responses, as evidenced through heart rate variability (HRV), for distinguishing between healthy individuals and DoC patients and for prognosticating patient outcomes.

Chimeric antigen receptor-T cell (CAR-T) immunotherapy has shown remarkable results for the treatment of certain hematologic malignancies. A redirection strategy that utilizes clinically relevant CAR-T cells in combination with adapter proteins may be an effective strategy to target other hematologic and solid cancers. We established a fusion antibody-based strategy with flexibility to target multiple tumor types in combination with a novel anti-leukocyte immunoglobulin-like receptor-B 4 (LILRB4) CAR-T cell.

Therapeutic genome editing of haematopoietic stem cells (HSCs) would provide long-lasting treatments for multiple diseases. However, the in vivo delivery of genetic medicines to HSCs remains challenging, especially in diseased and malignant settings. Here we report on a series of bone-marrow-homing lipid nanoparticles that deliver mRNA to a broad group of at least 14 unique cell types in the bone marrow, including healthy and diseased HSCs, leukaemic stem cells, B cells, T cells, macrophages and leukaemia cells.

Chimeric antigen receptor (CAR)-T cell therapy shows impressive efficacy treating hematologic malignancies but requires further optimization in solid tumors. Here, we developed a TMIGD2 optimized potent/persistent (TOP) CAR that incorporated the costimulatory domain of TMIGD2, a T and NK cell costimulator, and monoclonal antibodies targeting the IgV domain of B7-H3, an immune checkpoint expressed on solid tumors and tumor vasculature. Comparing second- and third-generation B7-H3 CARs containing TMIGD2, CD28, and/or 4-1BB costimulatory domains revealed superior antitumor responses in B7-H3.

Three new cyano-bridged Fe-Mo complexes assembled from the [Mo(CN)] unit, Fe ions, and three pentadentate NO ligands, namely {[FeH(dapab)][Mo(CN)]}·2HO·3.5MeCN (), [Fe(Hdapb)(HO)][Fe(Hdapb)(HO)][Mo(CN)]·4HO·3MeCN (), and [Fe(Hdapba)(HO)][Mo(CN)]·6HO () (Hdapab = 2,6-diacetylpyridine bis(2-aminobenzoylhydrazone), Hdapb = 2,6-diacetylpyridine bis(benzoylhydrazone), Hdapba = 2,6-diacetylpyridine bis(4-aminobenzoylhydrazone)), have been synthesized and characterized. Single-crystal structure analyses suggest that complex contains a one-dimensional (1D) chain structure where two Fe ions are bridged by the in situ generated [Mo(CN)] unit through two -cyanide groups into trinuclear FeMo clusters that are further linked by the amino of the ligand into an infinite chain.

A novel bis-bidentate nitronyl nitroxide radical based on triazolopyrimidine, NIT-2-TrzPm (NIT-2-TrzPm = (2-(2'-triazolopyrimidine)-4,4,5,5-tetramethyl-4,5-dihydro-1-imidazol-1-oxy-3-oxide)) and six new transition metal complexes of this ligand, namely [M(hfac)(NIT-2-TrzPm)]·CHCl (M = Mn (1Mn) and Co (2Co)), [M(hfac)](NIT-2-TrzPm) (M = Mn (3Mn) and Co (4Co)), [Mn(NIT-2-TrzPm)(MeOH)](ClO)·MeOH (5Mn), and [Co(NIT-2-TrzPm)(MeOH)](ClO)·4MeOH (6Co) were prepared and characterized structurally and magnetically. These complexes can be selectively synthesized by controlling the reaction ratio of M(hfac)·2HO to the radical ligand (for 1Mn to 4Co) or using metal perchlorates as the starting materials (for 5Mn and 6Co). Single crystal X-ray crystallographic analyses confirmed that 1Mn and 2Co are isostructural 3d-2p M-radical complexes, in which the NIT-2-TrzPm radical acts as a terminal bidentate ligand chelating to one 3d ion, while 3Mn and 4Co are isostructural 3d-2p-3d M-radical-M complexes with the NIT-2-TrzPm radical acting as a bridging ligand between two 3d ions.
