On the cover: Immunohistochemistry of a Mycobacterium tuberculosis granuloma during early infection. IL-10 receptor (red) is primarily found on macrophages (blue) rather than on T cells (green), indicating that IL-10 acts primarily on macrophages in granulomas. Wong, E. A., S. Evans, C. R. Kraus, K. D. Engelman, P. Maiello, W. J. Flores, A. M. Cadena, E. Klein, K. Thomas, A. G. White, C. Causgrove, B. Stein, J. Tomko, J. T. Mattila, H. Gideon, P. L. Lin, K. A. Reimann, D. E. Kirschner, and J. L. Flynn. 2020. IL-10 impairs local immune response in lung granulomas and lymph nodes during early Mycobacterium tuberculosis infection. J. Immunol. 204: 644–659.

Autoimmunity
Tolerogenic Dendritic Cells Generated by BAFF Silencing Ameliorate Collagen-Induced Arthritis by Modulating the Th17/Regulatory T Cell Balance
BAFF-silenced DCs exhibited an immature and tolerogenic phenotype.
BAFF-silenced DCs alleviated mouse CIA by modulating the Th17/Treg balance.
BAFF might be a promising genetic target to generate tolDCs for RA treatment.
IL-9 Controls Central Nervous System Autoimmunity by Suppressing GM-CSF Production
IL-9R−/− mice develop severe EAE with increased frequency of GM-CSF+ CD4+ T cells.
IL-9R−/− DCs induce GM-CSF in CD4+ T cells and contribute to disease worsening.
Clinical and Human Immunology
Impact of Early Antiretroviral Therapy Initiation on HIV-Specific CD4 and CD8 T Cell Function in Perinatally Infected Children
HIV-specific T cell responses persist despite long-term viral suppression.
Timing of ART initiation impacts the quality of the HIV-specific T cell responses.
Baseline PBMC transcriptome is different in HIV-infected children treated early.
Immune Regulation
Single and Synergistic Effects of Type 2 Cytokines on Eosinophils and Asthma Hallmarks
IL-5 regulates development in BM and accumulation of eosinophils in the lung.
IL-13 induces airway eosinophilia, AHR, and goblet cell metaplasia.
Development and transmigration of eosinophils are synergistically affected by both cytokines.
Functional Expression of the P2X7 ATP Receptor Requires Eros
The P2X7 receptor requires Eros as a chaperone to be expressed at plasma membrane.
The ATP-triggered IL-1β secretion in macrophages is strongly reduced without Eros.
Ca2+–Calcineurin Axis–Controlled NFAT Nuclear Translocation Is Crucial for Optimal T Cell Immunity in an Early Vertebrate
T cell signals trigger activation of multiple events in the teleost Ca2+–NFAT axis.
Tight regulation of Ca2+–NFAT is pivotal for teleost T cell activation and function.
Ca2+–NFAT is a primitive regulatory strategy that emerged in teleost T cells.
CD4+ T Cell–Derived NGAL Modifies the Outcome of Ischemic Acute Kidney Injury
Kidney CD4 T cells significantly increase Lcn2/NGAL expression following IR injury.
CD4 T cell Lcn2/NGAL protects against IR-induced AKI.
Lcn2 expression increased in ischemic CD4 T cells from human kidney.
Differential Induction of SOCS Isoforms by Leishmania donovani Impairs Macrophage–T Cell Cross-Talk and Host Defense
L. donovani induces SOCS1 in BMMфs by PI3K/Akt/Egr2 and IDO/kynurenine pathway.
PGE2 from infected BMMфs activates cAMP/PKA-mediated SOCS3 expression in T cells.
This inhibited STAT1- and STAT4-mediated IFN-γ and IL-12 synthesis in immune cells.

Novel TLR triagonist platforms have adjuvant activity in vivo.
The TLR triagonist adjuvants tune immune responses to subunit vaccination.
Naringenin Enhances the Antitumor Effect of Therapeutic Vaccines by Promoting Antigen Cross-Presentation
Enhanced Ag cross-presentation by naringenin is due to moderate ROS induction.
Naringenin potentially facilitates therapeutic vaccines against cancers or viruses.
Flavonoids manipulate intracellular ROS, making them excellent immunomodulators.

Brucella Infection Regulates Thioredoxin-Interacting Protein Expression to Facilitate Intracellular Survival by Reducing the Production of Nitric Oxide and Reactive Oxygen Species
Brucella decreased TXNIP to promote its intracellular growth in macrophages.
Reduced TXNIP promotes Brucella intracellular growth via reduction of NO and ROS.
The expression of iNOS and the production of NO were dependent on the Brucella T4SS.
IL-10 Impairs Local Immune Response in Lung Granulomas and Lymph Nodes during Early Mycobacterium tuberculosis Infection
IL-10 is not detrimental to early M. tuberculosis infection outcome.
Lack of IL-10 influences immune responses and fibrosis in granulomas.
Modeling predicts that prolonged lack of IL-10 leads to improved infection outcomes.
Neutrophils Enhance Their Own Influx to Sites of Bacterial Infection via Endosomal TLR-Dependent Cxcl2 Production
Neutrophils produce high levels of Cxcl2 in response to whole bacteria.
Cxcl2 production depends on sensing of bacterial nucleic acids by TLR7, 9, and 13.
Cxcl2 acts autocrinously to enhance antibacterial activities and its own production.
