Hepatolithiasis: Epidemiology, presentation, classification and management of a complex disease
World J Gastroenterol. 2024 Apr 7;30(13):1836-1850. doi: 10.3748/wjg.v30.i13.1836.ABSTRACTThe term hepatolithiasis describes the presence of biliary stones within the intrahepatic bile ducts, above the hilar confluence of the hepatic ducts. The disease is more prevalent in Asia, mainly owing to socioeconomic and dietary factors, as well as the prevalence of biliary parasites. In the last century, owing to migration, its global incidence has increased. The main pathophysiological mechanisms involve cholangitis, bile infection and biliary strictures, creating a self-sustaining cycle that perpetuates the disease, frequently c...

Streptococcus pneumoniae endopeptidase O induces trained immunity against numerous pathogen infections, a key role for G-CSF
Clin Immunol. 2024 Apr 23:110226. doi: 10.1016/j.clim.2024.110226. Online ahead of print.ABSTRACTAntibiotic resistance and the surge of infectious diseases during the pandemic present significant threats to human health. Trained immunity emerges as a promising and innovative approach to address these infections. Synthetic or natural fungal, parasitic and viral components have been reported to induce trained immunity. However, it is not clear whether bacterial virulence proteins can induce protective trained immunity. Our research demonstrates Streptococcus pneumoniae virulence protein PepO, is a highly potent trained immun...

Transcript tinkering: RNA modifications in protozoan parasites
Curr Opin Microbiol. 2024 Apr 24;79:102477. doi: 10.1016/j.mib.2024.102477. Online ahead of print.ABSTRACTApicomplexan and trypanosomatid parasites have evolved a wide range of post-transcriptional processes that allow them to replicate, differentiate, and transmit within and among multiple different tissue, host, and vector environments. In this review, we highlight the recent advances that point toward the regulatory potential of RNA modifications in mediating these processes on the coding and noncoding transcriptome throughout the life cycle of protozoan parasites. We discuss the recent technical advancements enabling t...

Intricate balance of dually-localized catalase modulates infectivity of Leptomonas seymouri (Kinetoplastea: Trypanosomatidae)
Int J Parasitol. 2024 Apr 23:S0020-7519(24)00077-8. doi: 10.1016/j.ijpara.2024.04.007. Online ahead of print.ABSTRACTNearly all aerobic organisms are equipped with catalases, powerful enzymes scavenging hydrogen peroxide and facilitating defense against harmful reactive oxygen species. In trypanosomatids, this enzyme was not present in the common ancestor, yet it had been independently acquired by different lineages of monoxenous trypanosomatids from different bacteria at least three times. This observation posited an obvious question: why was catalase so "sought after" if many trypanosomatid groups do just fine without it...

Biophysical Evidence for the Amyloid Formation of a Recombinant Rab2 Isoform of Leishmania donovani
CONCLUSION: To our knowledge, this is the first study to report in vitro amyloid-like behaviour of Rab proteins in L donovani. This study provides a novel opportunity to understand the complete biophysical characteristics of Rab2 protein of the lower eukaryote, L. donovani.PMID:38661034 | DOI:10.2174/0109298665299157240327084614 (Source: Protein and Peptide Letters)

Exploring the modulatory influence on the antimalarial activity of amodiaquine using scaffold hybridisation with ferrocene integration
Eur J Med Chem. 2024 Apr 16;271:116429. doi: 10.1016/j.ejmech.2024.116429. Online ahead of print.ABSTRACTAmodiaquine (AQ) is a potent antimalarial drug used in combination with artesunate as part of artemisinin-based combination therapies (ACTs) for malarial treatment. Due to the rising emergence of resistant malaria parasites, some of which have been reported for ACT, the usefulness of AQ as an efficacious therapeutic drug is threatened. Employing the organometallic hybridisation approach, which has been shown to restore the antimalarial activity of chloroquine in the form of an organometallic hybrid clinical candidate fe...
