CUTTING EDGE
Cutting Edge: ATP13A2 Is an Endolysosomal Regulator of TLR9/7 Activation in Human Plasmacytoid Dendritic Cells
Human pDCs express ATP13A2 in their endolysosomal compartments.
ATP13A2-mediated polyamine transport regulates TLR9/7 activation in pDCs.
ATP13A2 knockdown increases endosomal pH and mtROS, which dampens pDC activation.
CLINICAL AND HUMAN IMMUNOLOGY
Functional Heterogeneity of Umbilical Cord Blood Monocyte-Derived Dendritic Cells
UCB monocytes generate mature MoDCs with differences in cytokine and coreceptor profiles.
UCB-MoDCs present avid endocytosis and chemokine-mediated migratory behavior.
The allostimulatory capacity of UCB-MoDCs is reduced for CD4+ but not CD8+ T lymphocytes.
IMMUNE REGULATION
Diminished γδ T Cells during Murine Allergic Skin Inflammation Is Mediated by IL-4 Signaling in Keratinocytes
IL-4 signaling in keratinocytes mediates wound healing.
IL-4 signaling in keratinocytes controls DETC homeostasis.
IL-4 controls keratinocyte production of IL-15.
Activated PI3Kδ Specifically Perturbs Mouse Regulatory T Cell Homeostasis and Function Leading to Immune Dysregulation
Treg-specific aPIK3CD expression promotes Teff activation despite increased Treg frequency.
Foxp3-aPIK3CD mice exhibit spontaneous germinal centers and increased Tfh and autoantibodies.
Defective Treg fitness and increased PD-1 contribute to immune dysregulation.
IMMUNOTHERAPY AND VACCINES
Engineering Dimeric EGFR-directed IgA Antibodies Reveals a Central Role of CD147 during Neutrophil-mediated Tumor Cell Killing of Head and Neck Squamous Cancer Cells
Engineered IgA enhanced neutrophil-mediated cytotoxicity of HPV+ HNSCC.
Engineered dimeric IgA outperforms monomeric variants in Fab-mediated mechanisms.
CD147 is critical in target–effector cell cross-talk during neutrophil-mediated ADCC.
INFECTIOUS DISEASE AND HOST RESPONSE
Human Alveolar and Monocyte-Derived Human Macrophage Responses to Mycobacterium tuberculosis
M. tuberculosis infected human AMs have a unique transcriptome comparedwith MDMs.
IFNA8, Type I IFN pathway, and DNA sensors are upregulated in TB-infected AMs versus MDMs.
IFNA8 induces a distinct transcriptional program in MDMs compared to other IFNs.
Plasmodium yoelii Infection Enhances the Expansion of Myeloid-Derived Suppressor Cells via JAK/STAT3 Pathway
P. yoelii infection induced an elevation in immunosuppressive MDSCs.
GM-CSF/IL-6 activated MDSCs via JAK/STAT3 signaling upon P. yoelii infection.
Depletion of MDSCs enhanced Th1-biased immune responses to P. yoelii infection.
INNATE IMMUNITY AND INFLAMMATION
RNF216 Inhibits the Replication of H5N1 Avian Influenza Virus and Regulates the RIG-I Signaling Pathway in Ducks
duRNF216 interacts with duTRAF3 and degrades it to downregulate the RIG-I pathway.
duRNF216 targets AIV PB1 and damages viral polymerase assembly and activity.
AIV PB1 targets duRNF216 to attenuate negative regulation of duRIG-I pathway.
Unconventional IFNω-like Genes Dominate the Type I IFN Locus and the Constitutive Antiviral Responses in Bats
Bats generally have shorter IFN-I loci with more unique IFNω-like genes.
IFNω-like genes show the highest basal expression level.
The constitutive IFNω-like genes dominate the antiviral and antiproliferation functionality.
CCR1 and CCR2 Coexpression on Monocytes Is Nonredundant and Delineates a Distinct Monocyte Subpopulation
CCR2+ve and CCR1/2+ve monocytes are transcriptionally distinct.
CCR1/2+ve monocytes display a neutrophilic gene signature.
MOLECULAR AND STRUCTURAL IMMUNOLOGY
Structural and Biochemical Requirements for Secretory Component Interactions with Dimeric IgA
The secretory component D1 CDR3 loop plays an important role in binding to dIgA.
The formation of the SC D1–D3 interface stabilizes SIgA.
JC C-terminal residues influence dIgA assembly and mediate pIgR binding to dIgA.
Engineering Agonistic Bispecifics to Investigate the Influence of Distance on Surface-Mediated Complement Activation
Bispecifics have a critical end-to-end range for optimal complement activation.
Synthetic biology is useful to evaluate protein engineering to activate complement.

On the cover: DNA spacers are conjugated covalently to an antigen. This antigen is presented to bispecific nanobodies that recruit a component of the immune system; C1. Studying activation of C1 is relevant for the development of immunotherapeutics. Insights from these synthetic systems can potentially improve target selection for such therapeutics. Hamers, S. M. W.
