  • An atypical monocyte subset expressing CD56 is associated with COVID-19 severity.

  • CD56+ monocytes, showing a hyperinflammatory profile, can be induced by IFN-α.

J Immunol (2022) 209 (4): 660–664.

  • Self-renewing T cells responsive to PD-1 blockade are depleted from growing tumors.

  • Stability of self-renewing TCF1+CD8+ T cells correlates with immunotherapy response.

  • PI3Kδ inhibitor added to anti–PD-1 boosts TCF1+ T cell pool and lessens tumor growth.

ALLERGY AND OTHER HYPERSENSITIVITIES

J Immunol (2022) 209 (4): 665–674.

  • IgE+ plasmablasts secrete IgE, supporting the vicious cycle of allergy.

  • IgE+ plasmablasts correlate with clinical allergy severity and IgE secretion.

  • An acid wash approach quantifies IgE+ plasmablasts as an allergy severity biomarker.

ANTIGEN RECOGNITION AND RESPONSES

J Immunol (2022) 209 (4): 675–683.

  • pDCs bind Aspergillus hyphae, inducing activation/maturation.

  • pDC–A. fumigatus binding is mediated by CLRs, predominantly dectin-1.

  • Dectin-1 ligation indirectly and directly induces pDC activation and maturation.

J Immunol (2022) 209 (4): 684–695.

  • Neutralizing mAb 6C8 binds a unique epitope involving domain III and H1 of E protein.

  • 6C8 pressure leads to antigenic variation of TMUV in vitro.

AUTOIMMUNITY

J Immunol (2022) 209 (4): 696–709.

  • Tumor-bearing NOD mice model immune checkpoint inhibitor–associated autoimmunity.

  • γδT17 and Th17 type 3 immune cells contribute to ICI-associated thyroiditis.

  • IL-17A inhibition reduces thyroid autoimmunity but preserves the ICI antitumor response.

IMMUNE REGULATION

J Immunol (2022) 209 (4): 710–722.

  • SpRab11a drives bacterial resistance by regulating exosome formation.

  • Exosome drives bacterial resistance through exosomal Sp14-3-3.

  • Palmitate priming increases IL-6 secretion by monocytes stimulated with LPS.

  • Palmitate increases H3K9/H3K18 acetylation in monocytes.

  • H3K9/H3K18 acetylation associates with Il6 gene transcription.

J Immunol (2022) 209 (4): 742–750.

  • Soluble Msln and Muc16 regulate GATA6 expression in LCMs.

IMMUNE SYSTEM DEVELOPMENT

J Immunol (2022) 209 (4): 751–759.

  • NK cell inhibitory receptor repertoire skewing is observed already in bone marrow.

  • Repertoire skewing may partly be accounted for by selective proliferation.
