Antibacterial activities of novel peptide nucleic acids targeting <em>Salmonella</em> penicillin-binding proteins
Salmonella is a significant global enteric pathogen with a high incidence of multidrug resistance (MDR), which limits therapeutic options and necessitates the development of novel treatments. Antisense peptide nucleic acids (PNAs), which target essential bacterial genes, have demonstrated potential as antibacterial agents by effectively inhibiting the growth of various pathogens. Peptidoglycan (PG) has historically been one of the central targets for antibiotics in the ongoing battle against...
Epicutaneous application of house dust mite induces allergic skin inflammation and atopic march to the lung upon airway allergen challenge
Atopic dermatitis (AD) in infants is associated with increased risk of developing other allergic diseases, including asthma. This progression is known as atopic march (AM). We established a murine AM model by first inducing AD-like skin inflammation to house dust mite (HDM) allergen. Mice were subsequently challenged with HDM delivered to the lung. Our data show that epicutaneous sensitization with HDM increased serum IgE, ear thickness, and immune cell infiltration into the skin, accompanied by...
Molecular Characterization of Rift Valley Fever Virus From the 2025 Outbreak in Northern Senegal Reveals Lineage H Persistence and Key Polymerase Mutations
Rift Valley fever virus (RVFV) is a mosquito-borne phlebovirus that causes severe febrile and hemorrhagic illness in humans. In September 2025, an outbreak in northern Senegal led to 119 confirmed infections and 15 deaths as of October 7, 2025. We performed rapid genomic sequencing to characterize the virus responsible for this epidemic. RNA from RT-qPCR-confirmed samples was sequenced using the Twist Comprehensive Viral Research Panel on an Illumina iSeq 100 platform. Consensus genomes were...
Chromosome compartment assembly is essential for subtelomeric gene silencing in trypanosomes
Genome three-dimensional organization is essential for eukaryotic gene expression. The chromosomes of the pathogen Trypanosoma brucei contain hundreds of silent variant surface glycoprotein (VSG) genes in subtelomeric regions. T. brucei transcribes a single VSG gene and periodically changes the VSG expressed, altering its surface coat to escape host antibodies by antigenic variation. We show that T. brucei core and subtelomeric chromosome compartments are separated by distinct boundaries and...
Variation in surface protein expression leads to heterogeneous Trypanosoma cruzi populations during host cell infection
Trypanosoma cruzi possesses hundreds of genes associated with pathogenesis. The extent and organization of this diverse gene repertoire, expression, and role in infection remain unclear. Using accurate long-read sequencing and chromatin conformation capture, we assembled T. cruzi Sylvio X10 strain chromosomes from telomere-to-telomere. The genome provides accurate organization of multigene family genes, confirming their distribution in expanded clusters or scattered throughout the chromosomes....
<em>Brugia malayi</em> miRNAs and potential targets within the feline host (<em>Felis catus</em>)
Host specificity is a critical feature of the survival and proliferation of parasites. In the context of interactions with the host, numerous mechanisms have been identified, particularly in parasitic helminths, that enable manipulation of the host immune system to enhance their own survival. The evolutionary history of these interactions often results in hosts becoming disease-tolerant or asymptomatic, even when burdened with a high number of worms, until a disruption in the host's immune...
