Complement C3 mediates adolescent social isolation‐induced hippocampal synaptic deficits and sex‐specific emotional dysfunction

open access: yesInterdisciplinary Medicine, EarlyView.
Adolescent social isolation disrupts hippocampal function and exacerbates emotional symptoms, with sex‐specific patterns, as shown by human studies. In mice, social isolation decreased hippocampal synaptic density and calcium signaling, upregulated complement proteins, and activated complement‐mediated microglial synaptic phagocytosis.

Paternal Exposure to the Neonicotinoid Pesticide Clothianidin Alters Sperm MicroRNA Profiles in Mice and Intergenerationally Reduces Locomotor Activity in Male Offspring

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Accumulating evidence suggests that paternal environmental factors have epigenetic effects on sperm and influence offspring. Neonicotinoid pesticides (NNs), which are widely used around the world, are known to affect offspring phenotypes through maternal exposure in mice, but the effect of the paternal exposure remains unknown.

The Role of Magnetic Resonance Spectroscopy (MRS), Diffusion‐Tensor‐Imaging (DTI) and Structural MRI in the Alzheimer's Disease and Mild Cognitive Impairment Diagnosis: A Review

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Alzheimer's disease (AD) is one of the most common neurological disorders affecting older adults, with approximately 7.2 million cases only in the United States. This number is projected to increase to 13.8 million in the United States by 2060, leading to increased expenditures for healthcare, long‐term care and hospice services. Consequently,

Basal Forebrain Volume and Concurrent Hallucinations and Mild Cognitive Impairment in Parkinson's Disease

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Visual hallucinations (VH) and mild cognitive impairment (MCI) often co‐occur in Parkinson's Disease (PD). Each symptom in isolation is associated with cholinergic basal forebrain (BF) atrophy. However, it is unclear whether BF integrity relates to one symptom preferentially or to their co‐occurrence, and whether this relationship ...

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.

GABA_{B} Receptors Regulate Chick Retinal Calcium Waves [PDF]

open access: yes, 2001
Correlated spiking activity and associated Ca²⁺ waves in the developing retina are important in determining the connectivity of the visual system. Here, we show that GABA, via GABA_{B} receptors, regulates the temporal characteristics of Ca²⁺ waves ...

Circadian Immunity and Vascular Inflammation in Cardiovascular Disease Chronotherapy Windows: Time for a Re‐Assessment

open access: yesMed Research, EarlyView.
ABSTRACT Circadian rhythms orchestrate cardiovascular physiology by regulating immune and inflammatory pathways. Disruption of these rhythms profoundly alters vascular homeostasis, thereby promoting the onset and progression of cardiovascular diseases (CVD).

Biological Functions of Keratinocyte Cholinergic Receptors

open access: yesJournal of Investigative Dermatology Symposium Proceedings, 1997
Human epidermal keratinocytes possess cholinergic enzymes, which synthesize and degrade acetylcholine, and express both nicotinic and muscarinic classes of cholinergic receptors on their cell surfaces. These receptors bind acetylcholine and initiate cellular response.
