Exploration of Nirmatrelvir Derivatives as Optimized SARS‐CoV‐2 Antivirals

ChemMedChem, Volume 21, Issue 15, 14 August 2026.
Structure‐guided optimization of nirmatrelvir identifies aldehyde and dichloroacetamide warheads and a potency‐enhancing S4 thioamide. Crystal structures reveal an S2 rearrangement extending toward Cys44, suggesting a new covalent‐design opportunity.

B‐Cell Depletion Relative to Tumor Necrosis Factor Inhibition Extends the Duration of Viral Shedding in COVID‐19 Among Autoimmune Disease Patients: A Matched Prospective Cohort Study

ACR Open Rheumatology, Volume 8, Issue 8, August 2026.
Objective To investigate SARS‐CoV‐2 viral shedding duration in autoimmune patients using B cell depleting (BCD) therapy or tumor necrosis factor inhibitors (TNFi) and immunocompetent comparators. Methods We conducted a matched cohort analysis among participants in POSITIVES, a prospective study enrolling outpatients with acute COVID‐19 within five days

Portable Molecularly Imprinted Polymer Sensor for Rapid Swab‐Based Detection of Norovirus

Advanced Healthcare Materials, Volume 15, Issue 31, 21 August 2026.
This work reports a rapid, portable smartphone‐based sensor capable of detecting four norovirus genotypes from swab samples within 15 min. Sensor selectivity was validated through evaluation against four common live viruses. The swab‐based sampling process enabled simple sample preparation combined with the compact detection system, supporting use of ...

ZDHHC18‐Mediated Palmitoylation of ORF3a Promotes SARS‐CoV‐2 Pathogenesis by Antagonizing TRIM16‐Mediated Ubiquitination and Proteasomal Degradation

Advanced Science, Volume 13, Issue 43, 3 August 2026.
Palmitoylation by ZDHHC18 blocks ORF3a K27‐linked ubiquitination mediated by TRIM16, thereby preventing its proteasomal degradation and strengthening viral pathogenesis. Targeting palmitoylation through a pharmacological inhibitor (2‐BP), a competitive inhibitory peptide (OPIP), or adenovirus‐mediated knockdown of ZDHHC18 expression presents a ...

A Humanized Anti‐gD Broadly Neutralizing Antibody Confers Complete Post‐Exposure Protection Against Pseudorabies Virus

Advanced Science, Volume 13, Issue 46, 17 August 2026.
Pseudorabies virus (PRV), an emerging zoonotic α‐herpesvirus, causes life‐threatening human encephalitis. We identified a broad‐spectrum neutralizing antibody 6F7 targeting PRV gD. It blocks gD‐Nectin‐1 binding and membrane fusion, inhibiting replication across all PRV variants, representing a promising candidate for anti‐PRV therapy.

Mycobacterium tuberculosis and SARS‐CoV‐2 Co‐Infection: An Efficient Cell Model to Study Lung Host–Pathogen Interactions

Current Protocols, Volume 6, Issue 8, August 2026.
Abstract In less than a year, SARS‐CoV‐2 managed to displace Mycobacterium tuberculosis (Mtb) as the leading cause of death worldwide due to a single infectious agent. Both pathogens affect the respiratory tract, mainly the lungs. However, the impact that a possible Mtb + SARS‐CoV‐2 co‐infection can have on the host response is still unknown. Herein we

A Bacterial Microbiome Is Dispensable for the Induction of CD8 T Cell Exhaustion

European Journal of Immunology, Volume 56, Issue 8, August 2026.
We infected Germ‐free and normal SPF mice infected with strains of LCMV that cause chronic infections. In both types of mice, T cell exhaustion progressed to similar levels. Thus, the microbiome is dispensable for the induction of T cell exhaustion.

SARS‐CoV‐2 Neutralization Breadth Is Shaped by Variant Exposure and Immune History

Journal of Medical Virology, Volume 98, Issue 8, August 2026.
ABSTRACT Despite widespread COVID‐19 vaccination, emerging SARS‐CoV‐2 variants continue to evade neutralizing responses. To determine how exposure history influences neutralizing breadth against SARS‐CoV‐2, plasma collected from 46 participants in the Clinical, Virological and Immunological COVID‐19 study cohort (CVIC) was analyzed.

SARS‐CoV‐2 mRNA Vaccination Induces Neutralizing Antibodies and Type I IFN Changes in People Living With HIV

Journal of Medical Virology, Volume 98, Issue 8, August 2026.
ABSTRACT This study examined changes in anti‐Spike (anti‐S) antibodies (Abs) and type I interferon (IFN‐I) following the BNT162b2 vaccine in people living with HIV (PLWH) and analyzed the impact of demographic and immunological factors. In total, 75 PLWH and 28 healthy donors were followed at baseline (T0), at the second dose (T1), after the second ...
