CUTTING EDGE

CLINICAL AND HUMAN IMMUNOLOGY

J Immunol (2023) 210 (12): 1867–1881.

  • The rate of the MCAM+CD161Th17 subset was positively correlated with psoriasis severity.

  • The MCAM+CD161Th17 subset expressed CD83 more frequently than did the other subsets.

  • CD83 led to Tc17 proliferation, and exogenous IL-17A drove IL-17A production of Tc17.

J Immunol (2023) 210 (12): 1882–1888.

  • Reference functions describe human T lymphocyte densities as a function of age.

  • Lymphocyte counts linearly increase for the first half a year before declining.

  • CD4 and CD8 T cell percentages follow a “wavy” trajectory over time.

IMMUNE REGULATION

J Immunol (2023) 210 (12): 1889–1898.

  • A single Tox mRNA encodes two proteoforms with different N-termini.

  • Truncated TOX is translated by leaky scanning and regulated by cell context.

  • Alternative TOX proteins have overlapping but distinct effects on gene expression.

J Immunol (2023) 210 (12): 1899–1912.

  • ZIKV infection inhibits Twist1 expression and trophoblast migration.

  • Twist1 interacts with IRF9 and provides protection against ZIKV infection.

  • IFN-β inhibits Twist1 expression.

IMMUNOGENETICS

J Immunol (2023) 210 (12): 1913–1924.

  • CXCR4 mutation in WHIM patients and mice elevates blood CD4/CD8 T cell ratios.

  • WHIM CD8 T cells accumulate in the thymus and bone marrow of mice.

  • T cell lymphopenia in WHIM mice is ameliorated by the CXCR4 antagonist AMD3100.

IMMUNOTHERAPY AND VACCINES

J Immunol (2023) 210 (12): 1925–1937.

  • S- and N-predicted epitopes are antigenic for sera of infected patients.

  • Vaccination with rBCG leads to neutralization against virus and cytokine responses.

  • Oral prenol protects mice from SARS-CoV-2 spike S1 toxicity.

J Immunol (2023) 210 (12): 1950–1961.

  • Memory generation from CD4 effectors is proportional to their avidity for Ag/APC.

  • TCR avidity regulates autocrine IL-2 and thus regulates their survival and function.

J Immunol (2023) 210 (12): 1990–2000.

  • Plasma RNAs are upregulated and miRNA profiles altered in severe blunt polytrauma.

  • Plasma RNAs and ex-miRNAs of injured mice activate innate immunity via TLR7.
