AI Article Synopsis

  • The public health impact of cytomegalovirus (CMV) has spurred interest in developing vaccines to combat it.
  • Clinical studies for these vaccines face challenges due to the low incidence of congenital CMV, which complicates proving their effectiveness.
  • Insights from other congenital disease vaccines like rubella and Zika, along with regulatory considerations, are important for designing studies aimed at preventing CMV-related complications.

Article Abstract

The considerable public health burden due to cytomegalovirus (CMV) supports current interest in vaccine development. Clinical studies intended to support regulatory action should be designed to demonstrate substantial evidence of effectiveness. However, design and conduct of clinical endpoint studies may be hampered by low incidence of disease, especially for congenital CMV. Discussion and experience from other vaccines directed against congenital disease (including rubella and Zika) may be instructive. This article summarizes current scientific and US regulatory considerations related to design of studies of vaccines intended to prevent congenital CMV and complications of CMV in transplantation, as discussed at the 2018 workshop entitled "Cytomegalovirus Infection: Advancing Strategies for Prevention and Treatment."

Hair follicle (HF) development and pigmentation are complex processes governed by various signaling pathways, such as TGF-β and FGF signaling pathways. Nestin + (neural crest like) stem cells are also expressed in HF stem cells, particularly in the bulge and dermal papilla region. However, the specific role and differentiation potential of these Nestin-positive cells within the HF remain unclear, especially regarding their contribution to melanocyte formation and hair pigmentation.

Obesity, often driven by high-fat diets (HFD), is a major global health issue, necessitating effective preventive measures. Tetragonia tetragonoides, a plant with known medicinal properties, has not been extensively studied for its effects on HFD-induced obesity and related genetic changes in mice. This study explores the impact of Tetragonia tetragonoides extract (TTE; 300 mg/kg) on obesity-related traits in C57BL/6J male mice, with a focus on transcriptomic changes in the liver and white adipose tissue (WAT).

Objective: Cervical cancer is a common malignancy among women, and radiotherapy remains a primary treatment modality across all disease stages. However, resistance to radiotherapy frequently results in treatment failure, highlighting the need to identify novel therapeutic targets to improve clinical outcomes.

Methods: The expression of molecule interacting with CasL-2 (MICAL2) was confirmed in cervical cancer tissues and cell lines through western blotting (WB) and immunohistochemistry (IHC).

The connection between metabolic reprogramming and tumor progression has been demonstrated in an increasing number of researches. However, further research is required to identify how metabolic reprogramming affects interpatient heterogeneity and prognosis in clear cell renal cell carcinoma (ccRCC). In this work, single-cell RNA sequencing (scRNA-seq) based deconvolution was utilized to create a malignant cell hierarchy with metabolic differences and to investigate the relationship between metabolic biomarkers and prognosis.

Uropathogenic Escherichia coli (UPEC) is a major cause of urinary tract infections (UTIs). Invasion into bladder epithelial cells (BECs) on the bladder luminal surface via type 1 fimbria is the first critical step in UPEC infection. Although type 1 fimbria expression increases during UPEC invasion of BECs, the underlying regulatory mechanisms remain poorly understood.
