Widespread SARS‐CoV‐2 Transmission Despite Limited Reported Cases and Clinical Disease: Exploring the Role of Pre‐Existing Humoral Immunity to SARS‐CoV‐2 in Eastern Sierra Leone

Immunity, Inflammation and Disease, Volume 14, Issue 5, May 2026.
ABSTRACT Background Since December 2019, SARS‐CoV‐2 has infected over 700 million people and caused > 7 million deaths. While much of the global north was severely affected, sub‐Saharan Africa was relatively spared. Possible reasons include a younger population, fewer comorbidities, and pre‐existing immunity.

AP‐1‐Targeting Decoy Oligonucleotides: Mechanisms and Therapeutic Potential as Modulators of Inflammatory Pathways

Journal of Cellular and Molecular Medicine, Volume 30, Issue 9, May 2026.
ABSTRACT Numerous cellular functions, such as apoptosis, proliferation, differentiation, survival, transformation and cell migration, are regulated by a crucial transcription factor called activator protein 1 (AP‐1). Growing evidence indicates that AP‐1 is involved in severe conditions like fibrosis, cancer, and organ damage, as well as inflammatory ...

New Lineage of Lassa Virus, Togo, 2016

Emerging Infectious Diseases, 2018
We describe a strain of Lassa virus representing a putative new lineage that was isolated from a cluster of human infections with an epidemiologic link to Togo. This finding extends the known range of Lassa virus to Togo.

Olink Proteomics Reveals CCL2 Aggravates Perihematomal Edema After Intracerebral Hemorrhage in High‐Altitude Migrants Via CCR2/NF‐κB‐Mediated Blood–Brain Barrier Disruption

CNS Neuroscience &Therapeutics, Volume 32, Issue 4, April 2026.
Using high‐altitude migrants and rat models, we demonstrated CCL2 is a key inflammatory factor exacerbating high‐altitude ICH injury: long‐term high‐altitude exposure increases baseline CCL2 levels, and ICH triggers a sharp increase in CCL2 levels, which drives inflammatory storm amplification, BBB disruption, and neurological deficits. Inhibiting CCL2/

Development and Qualification of a Pseudotyped Virus‐Based Microneutralisation Assay for Influenza D Virus

Influenza and Other Respiratory Viruses, Volume 20, Issue 4, April 2026.
ABSTRACT Background Epidemiological surveillance of influenza D virus (IDV) has gained increased priority following recent serological findings indicating its potential zoonosis in humans. In this context, it is crucial to develop strong, reproducible, reliable and scalable immunological assays that can be quickly implemented in the surveillance of new

From Lake Victoria to the Tap: Antibiotic Resistance and Pathogenic Contamination of Kisumu City Water Supply and Wastewater Network

Tropical Medicine &International Health, Volume 31, Issue 4, Page 547-559, April 2026.
ABSTRACT Waterborne diseases and antimicrobial resistance (AMR) pose mounting public health threats across sub‐Saharan Africa, particularly in rapidly urbanising regions dependent on untreated or poorly treated surface waters. This study applied shotgun metagenomic sequencing to characterise microbial communities, virulence factors and antibiotic ...
