The mechanism for polar localization of the type IVa pilus machine in Myxococcus xanthus

open access: yesmBio, 2023
Type IVa pili (T4aP) are important for bacterial motility, adhesion, biofilm formation, and virulence. This versatility is based on their cycles of extension, adhesion, and retraction.

Recent advances on the mechanisms regulating cholangiocyte proliferation and the significance of the neuroendocrine regulation of cholangiocyte pathophysiology [PDF]

open access: yes, 2013
Cholangiocytes are epithelial cells lining the biliary epithelium. Cholangiocytes play several key roles in the modification of ductal bile and are also the target cells in chronic cholestatic liver diseases (i.e., cholangiopathies) such as PSC, PBC ...

Imaging and 3D reconstruction of membrane protein complexes by cryo-electron microscopy and single particle analysis [PDF]

open access: yes, 2006
Cryo-electron microscopy (cryo-EM) in combination with single particle image processing and volume reconstruction is a powerful technology to obtain medium-resolution structures of large protein complexes, which are extremely difficult to crystallize and ...

Peribiliary glands are key in regeneration of the human biliary epithelium after severe bile duct injury [PDF]

open access: yes, 2019
Peribiliary glands (PBG) are a source of stem/progenitor cells organized in a cellular network encircling large bile ducts. Severe cholangiopathy with loss of luminal biliary epithelium has been proposed to activate PBG, resulting in cell proliferation ...

GPCRs in CAR‐T Cell Immunotherapy: Expanding the Target Landscape and Enhancing Therapeutic Efficacy

open access: yesAdvanced Science, EarlyView.
Chimeric antigen receptor T cell therapy faces dual challenges of target scarcity and an immunosuppressive microenvironment in solid tumors. This review highlights how G protein‐coupled receptors can serve as both novel targets to expand the therapeutic scope and functional modules to enhance CAR‐T cell efficacy.

GERD and Upper Aerodigestive Tract Cancer Risk: A Systematic Review and Meta‐Analysis

open access: yesThe Laryngoscope, EarlyView.
ABSTRACT Objective Gastroesophageal reflux disease (GERD) is highly prevalent, yet its association with upper aerodigestive tract (UADT) cancers beyond esophageal adenocarcinoma remains incompletely defined. This systematic review and meta‐analysis aimed to quantify the risk of specific UADT cancers in individuals with GERD.

Exocrine Gland Dysfunction in Parkinson's Disease: Pathophysiology, Clinical Manifestations, and Therapeutic Perspectives—A Narrative Review

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Non‐motor symptoms, especially autonomic dysfunction, are major contributors to disability and decreased quality of life in Parkinson's disease (PD). Despite being common and having a wide range of clinical facets, exocrine gland dysfunction is still not well recognized and managed.
