    In-Depth Virological and Immunological Characterization of HIV-1 Cure after CCR5Δ32/Δ32 Allogeneic Hematopoietic Stem Cell Transplantation

    Scientists characterized a case of long-term HIV-1 remission of a 53-year-old male who was carefully monitored for more than 9 years after allogeneic CCR5Δ32/Δ32 hematopoietic stem cell transplantation performed for acute myeloid leukemia.

    CD5 Expression by Dendritic Cells Directs T Cell Immunity and Sustains Immunotherapy Responses

    The authors demonstrated that CD5-expressing dendritic cells helped to prime T cell responses against melanoma, and were associated with survival in human patients and with immune rejection of tumors in mouse models.

    MTSS1 Curtails Lung Adenocarcinoma Immune Evasion by Promoting AIP4-Mediated PD-L1 Monoubiquitination and Lysosomal Degradation

    Researchers found that MTSS I-BAR domain containing 1 (MTSS1) was downregulated in lung adenocarcinoma, leading to PD-L1 upregulation, impairment of CD8+ lymphocyte function, and enhanced tumor progression.

    PHGDH-Mediated Endothelial Metabolism Drives Glioblastoma Resistance to Chimeric Antigen Receptor T Cell Immunotherapy

    Metabolome and transcriptome analyses of human and mouse glioblastoma tumors identified that phosphoglycerate dehydrogenase (PHGDH) expression and serine metabolism were preferentially altered in tumor endothelial cells.

    Reciprocal Interactions between Innate Immune Cells and Astrocytes Facilitate Neuroinflammation and Brain Metastasis via Lipocalin-2

    Scientists uncovered the intricate interactions between recruited innate immune cells and resident astrocytes in the brain metastatic niche that facilitate metastasis of melanoma and breast cancer.

    Trivalent Mosaic or Consensus HIV Immunogens Prime Humoral and Broader Cellular Immune Responses in Adults

    The double-blind randomized trial enrolled 105 healthy HIV-uninfected adults who received three doses of either a trivalent global mosaic, a group M consensus, or a natural clade B gp160 env DNA vaccine, followed by two doses of a heterologous modified vaccinia Ankara–vectored HIV-1 vaccine or placebo.

    An Adverse Tumor-Protective Effect of IDO1 Inhibition

    Researchers showed that indoleamine 2,3-dioxygenase 1 (IDO1) inhibition led to an adverse protection of melanoma cells to T cell-derived interferon-gamma. RNA sequencing and ribosome profiling showed that IFNγ shut down general protein translation, which was reversed by IDO1 inhibition.

    Nanobody-Mediated Complement Activation to Kill HIV-Infected Cells

    Investigators developed a novel therapeutic modality to direct complement activity to the surface of HIV-1-infected cells. The bispecific complement engager was comprised of a nanobody recruiting the complement-initiating protein C1q, and single-chain variable fragments of broadly neutralizing antibodies targeting the HIV-1 envelope protein.

    Immune Surveillance of Brain Metastatic Cancer Cells Is Mediated by IFITM1

    In vivo genome-wide CRISPR-Cas9 screening revealed that loss of interferon-induced transmembrane protein 1 (IFITM1) promoted brain colonization of human lung cancer cells.
