Farmakogenomika to dziedzina z pogranicza farmacji i genomiki. Zajmuje się ona badaniem wpływu występujących u pacjenta wariantów genów związanych z metabolizmem leków na jego reakcję na konkretny lek. Rolą testów farmakogenomicznych jest określenie tempa metabolizmu leków i wykorzystanie tej informacji w praktyce klinicznej.

Mikrobiota układu pokarmowego jest nieodzownym elementem właściwego funkcjonowania organizmu człowieka, bowiem drobnoustroje jelitowe i ich metabolity silnie wpływają na metabolizm gospodarza i funkcje odpornościowe, jak również przyczyniają się do biosyntezy witamin, produkcji hormonów jelitowych, utrzymania integralności bariery jelitowej i ochrony przed patogenami, a także trawienia i wchłaniania składników odżywczych. Coraz częściej podkreśla się istnienie zależności pomiędzy zaburzeniami składu mikrobioty jelit a pojawianiem się chorób metabolicznych, tj. otyłości czy cukrzycy typu 2.

Rak jelita grubego (RJG) jest jednym z najczęściej rozpoznawanych nowotworów złośliwych: co roku notowane jest około 1,9 miliona nowych przypadków. Pomimo opracowania metod umożliwiających jego wykrywanie na początkowym etapie choroby i wprowadzenia nowych, skuteczniejszych terapii, RJG plasuje się na drugim miejscu wśród przyczyn zgonów wywołanych nowotworami. Wyniki najnowszych badań podkreślają rolę transporterów kwasów tłuszczowych, tj.

Rak trzustki jest często występującym nowotworem o bardzo złych rokowaniach i agresywnym przebiegu. Podstawową przyczyn wysoce niekorzystnych rokowań pacjentów z rakiem trzustki jest jego długotrwale bezobjawowy rozwój, co powoduje postawienie diagnozy na etapie znacznego zaawansowania procesu nowotworowego. Pomimo szeroko zakrojonych badań nad uskutecznieniem diagnostyki i leczenia tego nowotworu, przeżywalność pacjentów wzrasta powoli i nieznacznie.

Avian reoviruses (ARVs) represent a significant economic burden on the poultry industry due to their widespread prevalence and potential pathogenicity. These viruses, capable of infecting a diverse range of avian species, can lead to a variety of clinical manifestations, most notably tenosynovitis/arthritis. While many ARV strains are asymptomatic, pathogenic variants can cause severe inflammation and tissue damage in organs such as the tendons, heart, and liver.

Persistence is a strategy used by many viruses to evade eradication by the immune system, ensuring their permanence and transmission within the host and optimizing viral fitness. During persistence, viruses can trigger various phenomena, including target organ damage, mainly due to an inflammatory state induced by infection, as well as cell proliferation and/or immortalization. In addition to immune evasion and chronic inflammation, factors contributing to viral persistence include low-level viral replication, the accumulation of viral mutants, and, most importantly, maintenance of the viral genome and reliance on viral oncoprotein production.

Coinfections with porcine circovirus types 2, 3, and 4 (PCV2, PCV3, and PCV4) are increasingly being detected in the swine industry. However, there is no commercially available vaccine which prevents coinfection with PCV2, PCV3, and PCV4. The development of a vaccine expressing capsid (Cap) fusion proteins of multiple PCVs represents a promising approach for broadly preventing infection with PCVs.

The objective of this study was to describe an outbreak of equine herpesvirus-1 myeloencephalopathy (EHM) in a population of aged equids. The outbreak was linked to the introduction of five healthy non-resident horses 15 days prior to the first case of acute recumbency. This fulminant EHM outbreak was predisposed by the grouping of the 33 unvaccinated animals in two large pens with shared water and feed troughs.

Mapping the Protein Phosphatase 1 Interactome in Human Cytomegalovirus Infection.

Viruses

December 2024

Division of Infectious Diseases and Tropical Medicine, Department of Medicine I, Medical University of Vienna, 1090 Vienna, Austria.

Protein phosphorylation is a crucial regulatory mechanism in cellular homeostasis. The human cytomegalovirus (HCMV) incorporates protein phosphatase 1 (PP1) into its tegument, yet the biological relevance and mechanisms of this incorporation remain unclear. Our study offers the first characterization of the PP1 interactome during HCMV infection and its alterations.

Recently, we demonstrated that the oncolytic Coxsackievirus B3 (CVB3) strain PD-H can be efficiently adapted to resistant colorectal cancer cells through dose-dependent passaging in colorectal cancer cells. However, the method is time-consuming, which limits its clinical applicability. Here, we investigated whether the manufacturing time of the adapted virus can be reduced by replacing the dose-based passaging with volume-based passaging.

The Temporal Order of Mixed Viral Infections Matters: Common Events That Are Neglected in Plant Viral Diseases.

Viruses

Departamento de Biología del Estrés y Patología Vegetal, Centro de Edafología y Biología Aplicada del Segura (CEBAS)-CSIC, C.P. 30100 Murcia, Spain.

Mixed infections of plant viruses are common in crops and represent a critical biotic factor with substantial epidemiological implications for plant viral diseases. Compared to single-virus infections, mixed infections arise from simultaneous or sequential infections, which can inevitably affect the ecology and evolution of the diseases. These infections can either exacerbate or ameliorate symptom severity, including virus-virus interactions within the same host that may influence a range of viral traits associated with disease emergence.

Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease caused by the JC polyomavirus (JCPyV). Based on the clinical criteria, PML is diagnosed via polymerase chain reaction (PCR) detection of JCPyV DNA in cerebrospinal fluid (CSF) in combination with neurological and imaging findings. Although the utility of CSF JCPyV testing using ultrasensitive PCR assays has been suggested, its potential requires further evaluation.
