Exclusively in mammals, the diaphragm muscle (DIAm) is the major inspiratory pump, which separates the thoracic and abdominal cavities. With DIAm contraction a negative intrathoracic and positive abdominal pressure are generated (i.e., transdiaphragmatic pressure (Pdi). During breathing,the DIAm is very active, with a duty cycle (time active vs inactive) similar to that of the heart. Like the heart, this is a pump that cannot fail! Thus, in controlling breathing, the nervous system must activate DIAm to accomplish pump function while avoiding fatigue. The timing of DIAm activations must also be coordinated with activation of the upper airway muscles (the pipes) to avoid airway occlusion and aspiration, the intercostal and abdominal muscles to appropriately stiffen the body cavities. Similarly, neural control and coordination of the DIAm in non-ventilatory behaviors (airway protection, swallowing, vocalization and voiding) is equally complex, with coordinated activation of the DIAm and abdominal muscles. It is becoming increasingly clear that impaired non-ventilatory functions underlie the pathophysiology of a variety of medical conditions. In this review, we will delve into the detailed mechanistic underpinnings of the neural control of the DIAm and the symphonic coordination of its activation during breathing and other behaviors. We will attempt to move the field from considering the DIAm only as an inspiratory pump, emphasising neural control of airway, intercostal and abdominal muscles that must be coordinated with DIAm activation.","PeriodicalId":20193,"journal":{"name":"Physiological reviews","volume":"4 1","pages":""},"PeriodicalIF":33.6,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144604050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review examines the evolutionary origins of alcohol consumption and metabolism, focusing on the activity of alcohol dehydrogenase enzymes across species, which serve as key catalysts in alcohol oxidation. It also highlights recent advances in understanding central alcohol metabolism and updates on the potential clinical significance of non-oxidative pathways of alcohol metabolism and endogenous alcohol production, particularly in the context of liver disease. In addition, the review inspects factors that modulate alcohol metabolism, including genetic polymorphisms, biological sex, food intake, women's reproductive status, and clinical interventions such as medications and metabolic surgeries. Understanding these sources of variability in alcohol metabolism is crucial for identifying individual risk factors and tailoring strategies to reduce alcohol-related harm.

Despite the psychosocial burden of mpAGA in some affected individuals and associations with other morbidities, we portray mpAGA as an essentially physiological phenomenon in which defined hair follicle (HF) populations in developmentally preprogrammed scalp skin regions undergo a dramatic, but reversible (mini-)organ transformation in genetically predisposed individuals. Histologically, mpAGA exhibits progressive HF miniaturization (terminal-to-vellus conversion) and anagen shortening. Clinically, this results in a characteristic balding pattern of frontotemporal and vertex scalp skin, associated with telogen effluvium. It remains unclear how exactly androgens induce this phenotype, since neither androgen receptor polymorphisms nor changes in androgen serum or local androgen skin levels persuasively explain it. It also is as yet unresolved if mpAGA-associated HF transformation and hair cycle changes are primarily driven by the HF mesenchyme, e.g. by excessive emigration and/or reduced inductive potential of dermal papilla fibroblasts, or by intraepithelial events such as prostaglandin D2-dependent reduced HF epithelial stem cell progenitor generation. While critically revisiting our limited current understanding of mpAGA physiology and the role of mpAGA-associated genes we discuss potential targets for future therapeutic intervention beyond androgens and highlight selected dysregulated signaling pathways in mpAGA. We underscore mpAGA as an instructive, accessible model for interrogating under-investigated physiological roles of immune cells, oxidative stress, aging/senescence, and the microbiome in human organ remodeling and hair cycle regulation, and define major open research questions beyond androgen receptor- mediated signaling.","PeriodicalId":20193,"journal":{"name":"Physiological reviews","volume":"111 1","pages":""},"PeriodicalIF":33.6,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144594353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By now this dispute seems to have been largely reconciled. Lipophilic small molecule agonists of TPC2, mimicking either the NAADP or the PI(3,5)P<sub>2</sub> mode of channel activation, revealed, together with structural evidence, that TPC2 can change its selectivity for Ca<sup>2+</sup> versus Na<sup>+</sup> in a ligand-dependent fashion (N- vs. P-type activation).

In this review, we summarize the latest discoveries on the role of ACE2 in glucose homeostasis and regulation of metabolism. In the endocrine pancreas, ACE2 is expressed at low levels in β-cells, but loss of its expression inhibits glucose-stimulated insulin secretion and impairs glucose tolerance. Conversely, overexpression of ACE2 improved glycemia, suggesting that recombinant ACE2 might be a future therapy for diabetes. In the skeletal muscle of ACE2-deficient mice a progressive triglyceride accumulation was observed, whereas in diabetic kidney the initial increase in ACE2 is followed by a chronic reduction of expression in kidney tubules and impairment of glucose metabolism. At the intestinal level dysregulation of the enzyme alters the amino acid absorption and intestinal microbiome, whereas at the hepatic level ACE2 protects against diabetic fatty liver disease. Not least, ACE2 is upregulated in adipocytes in response to nutritional stimuli, and administration of recombinant ACE2 decreased body weight and increased thermogenesis. In addition to tissue-specific regulation of ACE2 function, the enzyme undergoes complex cellular posttranslational modifications that are changed during diabetes evolution, with at least proteolytic cleavage and ubiquitination leading to modifications in ACE2 activity.
