Blood transcriptomic discrimination of bacterial and viral infections in the emergency department: a multi-cohort observational validation study

open access: yesBMC Medicine, 2020
Background There is an urgent need to develop biomarkers that stratify risk of bacterial infection in order to support antimicrobial stewardship in emergency hospital admissions.

Livestock abundance predicts vampire bat demography, immune profiles, and bacterial infection risk [PDF]

open access: yes, 2018
Human activities create novel food resources that can alter wildlife–pathogen interactions. If resources amplify or dampen, pathogen transmission probably depends on both host ecology and pathogen biology, but studies that measure responses to ...

Mycobacterium tuberculosis sulfurtransferase SseA is activated by its neighboring gene product Rv3284

open access: yesFEBS Letters, EarlyView.
Tuberculosis remains a global health challenge and new therapeutic targets are required. Here, we characterized SseA, a sulfurtransferase from Mycobacterium tuberculosis involved in macrophage infection, and its interaction with the newly identified protein SufEMtb that activates SseA enzymatic activity.

TIGIT+Tfh show poor B-helper function and negatively correlate with SARS-CoV-2 antibody titre

open access: yesFrontiers in Immunology
Circulating follicular helper T cells (cTfh) can show phenotypic alterations in disease settings, including in the context of tissue-damaging autoimmune or anti-viral responses.

Foreign Sovereign Immunity, Individual Officials, and Human Rights Litigation [PDF]

open access: yes, 2010
For thirty years, international human rights litigation in U.S. courts has developed with little attention to a lurking doctrinal objection to the entire enterprise.

Protective immunity against Trypanosoma cruzi [PDF]

open access: yes, 2009
Upon infection, Trypanosoma cruzi triggers a strong immune response that has both protective and pathological consequences. In this work, several important questions regarding protective immunity are reviewed.

Neutrophil deficiency increases T cell numbers at the site of tissue injury in mice

open access: yesFEBS Letters, EarlyView.
In wild‐type mice, injury or acute inflammation induces neutrophil influx followed by macrophage accumulation. Mcl1ΔMyelo (neutrophil‐deficient) mice lack neutrophils, and in response to muscle injury show fewer macrophages and exhibit strikingly elevated T‐cell numbers, primarily non‐conventional “double‐negative” (DN) αβ and γδ T cells.

Optineurin functions for optimal immunity [PDF]

open access: yes, 2018
Optineurin (OPTN) was identified 20 years ago in a yeast-two-hybrid screen with a viral protein known to inhibit the cytolytic effects of tumor necrosis factor.

Development of visible light‐sensitive human neuropsin (OPN5) via single amino acid substitution

open access: yesFEBS Letters, EarlyView.
The present study determines a key amino acid residue, Lys91, for defining UV sensitivity of human OPN5. Heterologous action spectroscopy of the wild type and K91 mutants of OPN5 in HEK293T cells reveals that substitution of Lys91 with neutral (alanine) or acidic amino acids (glutamic or aspartic acids) causes substantial shifts in spectral sensitivity

HIV-1 Vpr antagonizes innate immune activation by targeting karyopherin-mediated NF-κB/IRF3 nuclear transport

open access: yeseLife, 2020
HIV-1 must replicate in cells that are equipped to defend themselves from infection through intracellular innate immune systems. HIV-1 evades innate immune sensing through encapsidated DNA synthesis and encodes accessory genes that antagonize specific ...
