Injectable 3D Vaccines Could Fight Cancer and Infectious Diseases
Researchers show a non-surgical injection of programmable biomaterial that spontaneously assembles in vivo into a 3D structure could fight and even help prevent cancer and also infectious disease such as HIV. [Press release from the Wyss Institute for Biologically Inspired Engineering discussing online prepublication in Nature Biotechnology] Press Release | Abstract

PUBLICATIONS (Ranked by impact factor of the journal)
Tissue-Resident Macrophage Enhancer Landscapes Are Shaped by the Local Microenvironment
Scientists profiled the dynamics of four histone modifications across seven tissue-resident macrophage populations. They show that a combination of tissue- and lineage-specific transcription factors form the regulatory networks controlling chromatin specification in tissue-resident macrophages. [Cell]

B Cell Super-Enhancers and Regulatory Clusters Recruit AID Tumorigenic Activity
Investigators studied activation-induced cytidine deaminase (AID)-mediated lesions in the context of nuclear architecture and the B cell regulome. They show that AID targets are not randomly distributed across the genome but are predominantly grouped within super-enhancers and regulatory clusters. [Cell]

Neutrophils Scan for Activated Platelets to Initiate Inflammation
Investigators report that neutrophil polarization within activated venules served to organize a protruding domain that engaged activated platelets present in the bloodstream. The selectin ligand PSGL-1 transduced signals emanating from these interactions, resulting in the redistribution of receptors that drive neutrophil migration. [Science] Abstract

Interleukin-10-Producing Plasmablasts Exert Regulatory Function in Autoimmune Inflammation
Researchers demonstrate that plasmablasts in the draining lymph nodes serve as interleukin-10 (IL-10) producers to limit autoimmune inflammation and emphasize the importance of plasmablasts as IL-10-producing regulatory B cells. [Immunity] Abstract | Graphical Abstract

Myeloid-Derived Suppressor Activity Is Mediated by Monocytic Lineages Maintained by Continuous Inhibition of Extrinsic and Intrinsic Death Pathways
Using genetic manipulation of cell death pathways, investigators found the monocytic suppressor-cell subset, but not the granulocytic subset, requires continuous c-FLIP expression to prevent caspase-8-dependent, RIPK3-independent cell death. [Immunity] Abstract | Graphical Abstract

Redox and Src Family Kinase Signaling Control Leukocyte Wound Attraction and Neutrophil Reverse Migration
Scientists studied the interactions between macrophages and neutrophils in response to tissue damage in zebrafish and found that macrophages contact neutrophils and induce resolution via neutrophil reverse migration. [J Cell Biol] Abstract | Editorial

Dermal Vγ4+γδ T Cells Possess a Migratory Potency to the Draining Lymph Nodes and Modulate CD8+ T Cell Activity Through Tnf-α Production
A recent study demonstrated that γδ T cells and cutaneous dendritic cells migrate from the skin to the draining lymph nodes (LNs). However, it remains unclear whether they regulate the antigen-specific immune response within the LNs. Researchers investigated their properties and role in the LNs using the Mycobacterium bovis bacille Calmette-Guérin infection model. [J Invest Dermatol] Abstract

Anti-CD33 Chimeric Antigen Receptor Targeting Of Acute Myeloid Leukemia
Researchers generated a second generation CD33-specific chimeric antigen receptor capable of redirecting cytolytic effector T cells against leukemic cells. The CD33-redirected T cells were effective in vivo, preventing leukemia development after prophylactic administration and delaying the progression of established disease in mice. [Haematologica] Abstract | Full Article

Homotypic NK Cell-to-Cell Communication Controls Cytokine Responsiveness of Innate Immune NK Cells
Using a specialized cell-laden microwell approach, scientists discovered that NK cells experiencing constant NK-to-NK contact exhibit a synergistic increase in activation status, cell proliferation, and anti-tumor function in response to IL-2 or IL-15. [Sci Rep] Full Article

Potentiation of Immunomodulatory Antibody Therapy with Oncolytic Viruses for Treatment of Cancer
Evidence is emerging that combination therapies using oncolytic viruses and agents targeting immune cosignaling receptors such as 4-1BB, PD-1, and CTLA-4 may work in concert to enhance antitumor immunity and therapeutic efficacy. [Mol Ther Oncolytics] Full Article

Early Trial of New Drug Shows Promise for Patients with Triple-Negative Breast Cancer
In patients with metastatic triple-negative breast cancer—a disease with no approved targeted therapies—infusion of pembrolizumab produced durable responses in almost one out of five patients enrolled in a Phase-Ib clinical trial. [Press release from University of Chicago Medical Center (Newswise, Inc.) discussing research presented at the 2014 San Antonio Breast Cancer Symposium (SABCS), San Antonio] Press Release

Immune Function Marker Does Not Predict Benefit of Trastuzumab in HER-2+ Breast Cancer Patients
A marker of immune function that predicts for better outcomes in patients treated with chemotherapy for triple negative breast cancer—the quantity of tumor-infiltrating lymphocytes (S-TILs) in a biopsy—appears irrelevant when trastuzumab is used.

Immunotherapy Shows Clinical Benefit in Relapsed Transplant Recipients
A multicenter Phase I trial of the immune checkpoint blocker ipilimumab found clinical benefit in nearly half of blood cancer patients who had relapsed following allogeneic stem cell transplantation.
