Pharmacological and genetic activation of cAMP synthesis disrupts cholesterol utilization in Mycobacterium tuberculosis.

PLoS Pathogens, 2022
There is a growing appreciation for the idea that bacterial utilization of host-derived lipids, including cholesterol, supports Mycobacterium tuberculosis (Mtb) pathogenesis.

Mechanisms of spinal glial activation in chemotherapy‐induced peripheral neuropathy: Focus on microglia and astrocytes

Ibrain, EarlyView.
Chemotherapy‐induced peripheral neuropathy (CIPN) remains a major clinical challenge, with central sensitization considered an important pathological mechanism in its occurrence and persistence. This review focuses on spinal astrocytes and microglia, systematically summarizing the pathological mechanisms of spinal glial cells involved in CIPN caused by

ADENYLYL CYCLASE ASSAYS TO MEASURE MACROPHAGE CHEMOTACTIC PROTEIN-1 RECEPTOR FUNCTION

Iranian Journal of Allergy, Asthma and Immunology, 2000
Adenylyl cyclase is a membrane-bound enzyme that catalyzes the conversion of ATP to cAMP. The inhibition of adenylyl cyclase was carried out by measuring the ability of the macrophage chemotactic protein-1 to inhibit the torskolin-induced enzyme activity.

Intracellular cAMP Signaling Pathway via G_s Protein-Coupled Receptor Activation in Rat Primary Cultured Trigeminal Ganglion Cells

Biomedicines, 2023
G protein-coupled receptors in trigeminal ganglion (TG) neurons are often associated with sensory mechanisms, including nociception. We have previously reported the expression of P2Y12 receptors, which are Gi protein-coupled receptors, in TG cells ...

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

Med 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).

Pulmonary granulocyte influx and impaired alveolar macrophage adenylyl cyclase responsiveness in developing respiratory distress

Mediators of Inflammation, 1993
Alveolar macrophages have recently been postulated as being involved in the aetiology of adult respiratory distress syndrome (ARDS). To evaluate their role, basal cyclic AMP levels and responsiveness of adenylyl cyclase alveolar macrophages were ...

Functional selectivity of GPCR-directed drug action through location bias. [PDF]

, 2017
G-protein-coupled receptors (GPCRs) are increasingly recognized to operate from intracellular membranes as well as the plasma membrane. The β 2 -adrenergic GPCR can activate G s -linked cyclic AMP (G s -cAMP) signaling from endosomes.

Adenylyl cyclase Rv1625c of Mycobacterium tuberculosis: a progenitor of mammalian adenylyl cyclases [PDF]

The EMBO Journal, 2001
The gene Rv1625c from Mycobacterium tuberculosis encodes a membrane-anchored adenylyl cyclase corresponding to exactly one-half of a mammalian adenylyl cyclase. An engineered, soluble form of Rv1625c was expressed in Escherichia coli. It formed a homodimeric cyclase with two catalytic centers. Amino acid mutations predicted to affect catalysis resulted

Psychiatric Disorders and Apathy in Mixed Movement Disorders Linked to ADCY5 (MxMD‐ADCY5)

Movement Disorders, EarlyView.
Abstract Background Mixed movement disorders linked to ADCY5 (MxMD‐ADCY5) represent a rare hyperkinetic movement disorder resulting from pathogenic variants in ADCY5. Psychiatric symptoms are suspected to be part of the phenotype. Objective The study aim was to assess psychiatric comorbidities in patients with MxMD‐ADCY5.

The role of mislocalized phototransduction in photoreceptor cell death of retinitis pigmentosa.

PLoS ONE, 2012
Most of inherited retinal diseases such as retinitis pigmentosa (RP) cause photoreceptor cell death resulting in blindness. RP is a large family of diseases in which the photoreceptor cell death can be caused by a number of pathways.
