Gill diseases may cause high mortalities in farmed Atlantic salmon. In seawater reared fish co-infections involving the epitheliocystis associated bacterium Ca. Branchiomonas cysticola, the microsporidian Desmozoon lepeophtherii, the causative agent of amoebic gill disease Paramoeba perurans and salmon gill poxvirus are common and histopathological lesions may be complex. Here, we report detection of these agents utilising multiplex real-time PCR and link the presence of agents to histopathologically visible gill lesions by in situ hybridisation (ISH) utilising RNAscope™. We show that Ca.

Background SARS-CoV-2 is a highly contagious virus that causes the disease COVID-19. We have recently reported that androgens regulate the expression of SARS-CoV-2 host entry factors ACE2 and TMPRSS2, and androgen receptor (AR) in lung epithelial cells. We also demonstrated that the transcriptional repression of the AR enhanceosome inhibited SARS-CoV-2 infection in vitro.

Japanese encephalitis virus (JEV), a member of the Flavivirus genus, is an important pathogen that causes human and animal infectious diseases in Asia. So far, no effective antiviral agents are available to treat JEV infection. Here, we found that LDLR is a host factor required for JEV entry. Berbamine significantly decreases the level of LDLR at the plasma membrane by inducing the secretion of LDLR via extracellular vesicles (EVs), thereby inhibiting JEV infection.

In situ hybridization (ISH) is a methodology by which nucleic acids are detected within fixed tissue samples. Recent advances in detection technology and target recovery have greatly enhanced the technique's ability to detect single mRNA molecules. Here we detail the fixation, paraffin embedding, sectioning, target recovery, and chromogenic detection of an mRNA (DvSSJ1), encoding for a membrane protein associated with the smooth septate junction (SSJ) in Western corn rootworm [Diabrotica virgifera (Dv)].

不同于其他头颈部鳞状细胞癌,人乳头状瘤病毒(HPV)相关口咽鳞状细胞癌(OPSCC)是一类具有 不同分子生物学发病机制、危险因素、临床病理特征的特殊疾病。HPV 阳性 OPSCC患者的预后明显优于 HPV 阴 性患者,因此 HPV 的检测对 OPSCC的诊断和治疗尤为重要。目前,国内外针对 OPSCC中 HPV 生物分子标志物 的检测方法多种多样,但仍然缺乏一个在该领域达成共识的规范化检测标准。本文围绕 OPSCC中 HPV 生物分子 标志物的研究现状做一总结,旨在为实验室以及临床上选择适合的生物分子标志物进行 OPSCC诊断提供借鉴。

Over the years the transactive response DNA-binding protein (TDP-43), a highly conserved 43 kDa nuclear protein, has been acknowledged as a vital protein in brain health and neuropathological disorders such as amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), Alzheimer's disease (AD), Lewy body dementia (LBD), and Parkinson disease (PD). Description of TDP-43 dates back to 1892 when neurologist Arnold Pick first described progressive dementia characterized by atrophy that diverged both clinically and pathophysiologically from AD.

Immune checkpoint blockade using PD-1 inhibition is an effective approach for treating a wide variety of cancer subtypes. While lower gastrointestinal (GI) side effects are more common, upper gastrointestinal adverse events are rarely reported. Here, we present a case of nivolumab-associated autoimmune gastritis. To elucidate the immunology underlying this condition, we leverage multiplexed ion beam imaging by time-of-flight (MIBI-TOF) to identify the presence and proportion of infiltrating immune cells from a single section of biopsy specimen.

Background: Somatosensation depends on primary sensory neurons of the trigeminal and dorsal root ganglia (DRG). Transcriptional profiling of mouse DRG sensory neurons has defined at least 18 distinct neuronal cell types. Using an advillin promoter, we have generated a transgenic mouse line that only expresses diphtheria toxin A (DTA) in sensory neurons in the presence of Cre recombinase. This has allowed us to ablate specific neuronal subsets within the DRG using a range of established and novel Cre lines that encompass all sets of sensory neurons.

Placental hypervascularization has been reported in pregnancy-related pathologies such as gestational diabetes mellitus (GDM). Nevertheless, the underlying causes behind this abnormality are not well understood. In this study, we addressed the expression of SUCNR1 (cognate succinate receptor) in human placental endothelial cells and hypothesized that succinate-SUCNR1 axis might play a role in the placental hypervascularization reported in GDM. We measured significantly higher succinate levels in placental tissue lysates from women with GDM relative to matched controls.
