Semaphorin-4D signaling in recruiting dental stem cells for vascular stabilization.
Stem Cell Res Ther

Applied Oral Sciences and Community Dental Care, Faculty of Dentistry, Prince Philip Dental Hospital, The University of Hong Kong, 34 Hospital Road, Sai Ying Pun, Hong Kong, Hong Kong SAR.
Background: Achieving a stable vasculature is crucial for tissue regeneration. Endothelial cells initiate vascular morphogenesis, followed by mural cells that stabilize new vessels. This study investigated the in vivo effects of Sema4D-Plexin-B1 signaling on stem cells from human exfoliated deciduous teeth (SHED)-supported angiogenesis, focusing on its mechanism in PDGF-BB secretion.

January 2025
Family medicine, School of Public Health and Community Medicine, Institute of Medicine, Sahlgrenska Academy, University of Gothenburg, Box 454, Göteborg, 40530, Sweden.
Background: Endogenous sex hormones in postmenopausal women have been associated with risk of cardiovascular diseases. The aim of this study was to determine the association between endogenous sex hormones and the revised Framingham Stroke Risk Profile (rFSRP) in postmenopausal women.
Methods: This is an observational cross-sectional study on the Vara-Skövde cohort, a Swedish population-based study for longitudinal surveillance of the development and progress of type 2 diabetes and hypertension.

Non-24-h sleep-wake disorder in blind patients without light perception is an orphan circadian rhythm sleep-wake disorder and is extremely rare in sighted people. Non-24-h sleep-wake disorder is characterized by insomnia and daytime sleepiness alternating with asymptomatic episodes. The frequency of symptomatic periods depends on the daily desynchronization of endogenous circadian pattern of each patient.

Background: A number of immunotherapeutic approaches have been developed and are entering the clinic. Bispecific antibodies (BsAbs) are one of these modalities and induce robust efficacy by endogenous T cells in several hematological malignancies. However, most of the treated patients experience only a temporary benefit.

State Key Laboratory of Pharmaceutical Biotechnology, Department of Biochemistry, School of Life Sciences, Nanjing University, Nanjing, 210023, China. Electronic address:
Given the pivotal role of the Eph-Ephrin signaling pathway in tumor progression, agonists or antagonists targeting Eph/Ephrin have emerged as promising anticancer strategies. However, the implications of glycosylation modifications within Eph/Ephrin and their targeted protein therapeutics remain elusive. Here, we identify that N-glycosylation within the receptor-binding domain (RBD) of ephrin B1 (EFNB1) is indispensable for its functional repertoire.
