Nicotine as an odorant : a biochemical and electrophysiological study of receptors for nicotine in the olfactory epithelium of the rat [PDF]

open access: yes
The results suggest that nicotine vapour stimulates an in vitro olfactory preparation in three strains of rat and two strains of mouse, in a manner similar to known odorants.

Targeting Inflammatory Alarmin S100A9 Modulates Activation of Pro‐Inflammatory Macrophage to Protect Nasal Epithelial Cells From LPS‐Induced Epithelial–Mesenchymal Transition

open access: yesMicrobiology and Immunology, EarlyView.
ABSTRACT Chronic rhinosinusitis with nasal polyps (CRSwNP) exhibits pronounced endotypic heterogeneity, with macrophages serving as key drivers of sustained mucosal inflammation. In this study, we identify S100A9 as a macrophage‐derived alarmin that is markedly elevated in CRSwNP tissues.

Infection control in the brain and the eye

open access: yesActa Ophthalmologica, EarlyView.
Abstract The Central Nervous System (CNS), comprising the brain and the eye, is considered to have a ‘privileged’ mechanism for dealing with immunological challenge (immune privilege, IP). CNS IP has been revealed through experiments using foreign protein antigens and cell and tissue alloantigens (grafts), but evidence for a role for IP in modulating ...

The Olfactory Nervous System Of Terrestrial And Aquatic Vertebrates

open access: yes, 2011
Animals in their natural milieu are surrounded by odors. These odors are rich source of information, and are perceived by sophisticated olfactory systems, that have evolved over time.

Reduction of Proliferating Olfactory Cells and Low Expression of Extracellular Matrix Genes Are Hallmarks of the Aged Olfactory Mucosa

open access: yesFrontiers in Aging Neuroscience, 2018
Background: The incidence of olfactory impairment increases with age; however, the detailed molecular and cellular mechanisms underlying this increase are yet to be determined.Methods: We examined the influence of aging on olfactory receptor neurons ...

Human brain matters: Navigating the neuropathology of COVID‐19

open access: yesBrain Pathology, EarlyView.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive

Expression of adiponectin receptor 1 in olfactory mucosa of mice

open access: yes, 2022
S.187-197AdipoR1 and AdipoR2 are receptors for the adipocyte-derived hormone adiponectin, which is an important regulator of glucose and lipid metabolism, and which has also been implicated in the control of food intake and energy homeostasis.

GIP in Cardiovascular and Kidney Disease: From Physiology to Pharmacology

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims To provide a comprehensive overview of the cardiovascular and renal effects of glucose‐dependent insulinotropic polypeptide (GIP) by integrating its physiological role with recent human trial data on tirzepatide, the first dual GIP and glucagon‐like peptide‐1 (GLP‐1) receptor agonist.

Variability in intracellular localization of D‐amino acid oxidase in choroid plexus epithelial cells

open access: yesThe FEBS Journal, EarlyView.
D‐amino acid oxidase (DAO) in choroid plexus epithelial cells (CPECs) shows vesicle‐like localization by histological and super‐resolution analyses. DAO colocalizes with peroxisomal, Golgi, endosomal, lysosomal, autophagosomal, and exosomal markers, indicating diverse subcellular distribution. This suggests DAO is transported within CPECs to metabolize

Novel convolution-based processing techniques for application in chemical sensing [PDF]

open access: yes
The electronic nose is a device developed to mimic the human olfactory system. Despite raising interest from applications in the field of medicine, quality control, environmental control and security, such devices remain inferior to their biological ...
