Agonist‐specific conformational dynamics at the β2‐adrenoceptor dictate allosteric modulation of Gαs signalling and bronchodilation

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose β2‐adrenoceptor (β2AR) agonists are the cornerstone of asthma therapy and promote bronchodilation through Gαs signalling in airway smooth muscle (ASM), but their efficacy is limited by β‐arrestin‐mediated β2AR desensitization.

Unveiling Gut Homeostasis Disruption in Sepsis: Towards an Integrated Mechanistic and Translational Roadmap

open access: yesCell Proliferation, EarlyView.
Elucidating the contribution of gut‐organ axes will provide new insights for developing combined therapeutic strategies against sepsis‐associated multiple organ dysfunction. ABSTRACT Sepsis, a life‐threatening clinical syndrome precipitated by a maladaptive host response to infection, is associated with substantial morbidity and high mortality rates ...

Spatiotemporal dynamics of β‐arrestin‐mediated Src activation in 5‐HT7 receptor signaling pathway

open access: yesThe FEBS Journal, EarlyView.
GPCRs induce distinct cellular responses via G protein‐ or β‐arrestin‐mediated signaling pathways. This study revealed that β‐arrestin‐biased 5‐HT7R ligand induces slow, sustained Src activation, contrasting with transient G protein‐mediated activation.

Cardiovascular β-Adrenergic Receptor Distribution and Function: Influence of Species, Sex, Age, and Tissue. [PDF]

open access: yesCompr Physiol
Estrogen modulates β‐AR signaling in a context‐dependent manner influenced by species, sex, age, tissue, and vascular health, highlighting challenges in translating findings from experimental models to human cardiovascular physiology. ABSTRACT Cardiovascular diseases remain the leading global cause of morbidity and mortality, with notable sex‐specific ...

Iloperidone treatment mitigates the Juvenile Huntington's Disease phenotype possibly via Sigma‐1 Receptor Modulation

open access: yesThe FEBS Journal, EarlyView.
We investigated the potential of iloperidone as an activator of Sigma‐1 receptor (S1R) neuroprotective function in juvenile Huntington's disease (jHD). We tested iloperidone on cortical neurons differentiated from patient‐derived iPSCs, demonstrating that it acts as a S1R agonist, decreasing apoptosis, huntingtin aggregation, and oxidative stress ...

The Role of Neuropeptide Y in Dental Pulp: Balancing Neurogenic Inflammation and Pain Modulation

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Background Dental pulp is a densely innervated, low‐compliance tissue in which neurogenic inflammation can rapidly escalate into oedema, raised intrapulpal pressure, microvascular compromise, and pain. While Substance P (SP) and Calcitonin gene‐related peptide (CGRP) are well‐established drivers of pulp vasodilation, the Neuroopeptide Y (NPY ...

Neural modulation of ocular immunity: Exploring a sympathetic‐macrophage neuroimmune link in the human ciliary body

open access: yesJournal of Anatomy, EarlyView.
Using microscopy and 3D confocal imaging on seven cadaveric eyes, we identified sympathetic nerves closely associated with β₂‐adrenergic receptor‐expressing macrophages in the human ciliary body (CB). These findings suggest a sympathetic‐macrophage neuroimmune link in the CB, potentially influencing ocular inflammation and degeneration, warranting ...

New Aspects of 2-Adrenergic Agonists

open access: yesJournal of Bahria University Medical and Dental College, 2015
Beta2-adrenergic receptor agonists is a class of medications that act on the 2-adrenergic receptors. They are mostly used to treat asthma and other respiratory problems at present.

Persistent Lactate Elevation in a Patient with Asthma Exacerbation and a Congenital Portosystemic Shunt: A Case Report and Literature Review

open access: yesReports
Background and Clinical Significance: When lactate production surpasses the body’s clearance capacity, hyperlactatemia (lactate ≥ 2 mmol/L) or lactic acidosis (lactate ≥ 4 mmol/L) can develop.
