The integrated cell culture quantitative reverse transcriptase PCR (ICC/qRT-PCR) method is used in our lab to detect enteroviruses in environmental waters. Typically we utilize monolayers of 3 cell lines; buffalo green monkey kidney (BGM), human colonic carcinoma (CACO-2) and African rhesus monkey kidney (MA104) with the intent of providing one or more permissive hosts to a wide range of enteroviruses. In this study the BGM cell line was used to compare poliovirus infectivity in conventional monolayer cultures to BGM cells in suspensions. Propagated virus was subsequently amplified by qRT-PCR. Our PCR data showed lower cycle threshold (Ct) values in the suspensions which corresponded to a higher rate of infectivity than that observed in the monolayers. The difference in Ct values was determined statistically significant by One-way ANOVA (0.000). Infecting BGM cells in suspensions required less hands-on time, less chance of contamination and was more cost effective than utilizing the conventional monolayer technique.

New treatment approaches are warranted for patients with advanced melanoma refractory to immune checkpoint blockade (ICB) or BRAF-targeted therapy. We designed BNT221, a personalized, neoantigen-specific autologous T cell product derived from peripheral blood, and tested this in a 3 + 3 dose-finding study with two dose levels (DLs) in patients with locally advanced or metastatic melanoma, disease progression after ICB, measurable disease (Response Evaluation Criteria in Solid Tumors version 1.1) and, where appropriate, BRAF-targeted therapy.

Parkinson's Disease (PD) is a progressive neurodegenerative condition, which is highly heterogeneous upon diagnosis. Brain extracellular matrix (ECM) accounts for 10-20 % of the total brain volume and is responsible for the physical organization of neuronal and glia cells. Blood-based biomarkers quantifying ECM fragments holds the potential as diagnostic and prognostic biomarkers.

Convergent data, across species, paint a compelling picture of the critical role of the gut and its resident microbiota in several brain functions and disorders. The chemicals mediating communication along these sophisticated highways of the brain-gut-microbiome (BGM) axis include both microbiota metabolites and classical neurotransmitters. Amongst the latter, GABA is fundamental to brain function where it mediates the majority of neuronal inhibition.

Safety and Efficacy of Immunization with a Late-Liver-Stage Attenuated Malaria Parasite.

N Engl J Med

November 2024

From Leiden University Center for Infectious Diseases, Leiden University Medical Center, Leiden (O.A.C.L., B.M.D.F-.F., J.P.R.K., G.V.T.R., J.J.J., S.C.C.-M., F.J.A.G., H.M.B.-R., E.I., E.C., E.W., E.L.H., R.M., C.J.J., M.R.), and the Department of Medical Microbiology, Radboud University Medical Center, Nijmegen (G.-J.G., M.V.-B., W.G., T.R.S., B.G.M., T.B., M.B.B.M.) - both in the Netherlands.

Background: Currently licensed and approved malaria subunit vaccines provide modest, short-lived protection against malaria. Immunization with live-attenuated malaria parasites is an alternative vaccination strategy that has potential to improve protection.

Methods: We conducted a double-blind, controlled clinical trial to evaluate the safety, side-effect profile, and efficacy of immunization, by means of mosquito bites, with a second-generation genetically attenuated parasite (GA2) - a single knockout NF54 parasite (sporozoite form) with extended development into the liver stage.

Cellular aging is considered as one of the main factors implicated in female infertility. We evaluated the expression of senescence-associated secretory phenotype (SASP) markers and additional molecular factors in an in vitro model of cellular aging. We induced genotoxic stress (UVB/UVA ray irradiation) in primary human endometrial cells obtained from female subjects of young reproductive age (<35 years of age).
