Article Abstract
As the first line of defence in the lung, alveolar macrophage contributes to maintaining lung immune homoeostasis. Characterized by the heterogeneity and plasticity, macrophages polarize into two pro-inflammatory and anti-inflammatory phenotypes regarding the biological and pathological environment. In the past decade, numerous studies have revolutionized the relationship between cellular metabolism and macrophage functions. Mitochondria dysfunctions, which results in altered cellular metabolic profile, were observed in the alveolar macrophages during chronic lung diseases. In addition, alveolar macrophages adapt metabolic reprogramming to produce an immune response against the pathogens. Here, we outline the role of mitochondria in the development of macrophage phenotypes and functions and highlight the mitochondrial dysfunction in the setting of chronic lung diseases. Lastly, we emphasize the therapeutic relevance of targeting metabolic pathways in alveolar macrophages, which may shed light on developing novel strategies against chronic lung diseases.

Chronic kidney disease and incident cancer risk: an individual participant data meta-analysis.
Br J Cancer
September 2025
School of Cardiovascular and Metabolic Health, University of Glasgow, Glasgow, UK.
Background: Studies examining the association of chronic kidney disease (CKD) with cancer risk have demonstrated conflicting results.
Methods: This was an individual participant data meta-analysis including 54 international cohorts contributing to the CKD Prognosis Consortium. Included cohorts had data on albuminuria [urine albumin-to-creatinine ratio (ACR)], estimated glomerular filtration rate (eGFR), overall and site-specific cancer incidence, and established risk factors for cancer.

Cardiovascular-kidney-metabolic (CKM) syndrome is a term that is increasingly used to describe interconnected conditions that lead to poor health outcomes, including cardiovascular disease, chronic kidney disease, type 2 diabetes, and obesity. Historically, there have been very few targeted pharmacotherapies available that have changed cardiovascular outcomes for people with CKM syndromes; however, over the past decade, new pharmacologic options have rapidly expanded, with strong evidence for cardiovascular and kidney protective benefits in CKM conditions. Of note, sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists have emerged as key therapeutic options and are now widely guideline-endorsed.

Background: Red and processed meat consumption is extensively linked to chronic disease risk in observational studies, with robust meta-analyses demonstrating significant positive associations for colorectal, breast, endometrial, and lung cancers, type 2 diabetes (T2DM), cardiovascular disease (CVD), and all-cause mortality. Dose-response relationships indicate elevated risks even at moderate intakes. Moreover, processed meats consistently show stronger detrimental effects than unprocessed red meats.

Air pollution is a significant public health issue that impacts lung health, particularly in vulnerable populations such as children, the elderly, and individuals with pre-existing respiratory conditions. Both natural and anthropogenic sources of air pollution give rise to a variety of toxic compounds, including particulate matter (PM), ozone (O₃), sulfur dioxide (SO₂), nitrogen dioxide (NO₂), carbon monoxide (CO), and polycyclic aromatic hydrocarbons (PAHs). Exposure to these pollutants is strongly associated with the development and exacerbation of respiratory diseases, including asthma, chronic obstructive pulmonary disease (COPD), lung cancer, and idiopathic pulmonary fibrosis (IPF).

Adaptation of intestinal helminths to vertebrates involved the evolution of strategies to attenuate host tissue damage to support parasite reproduction and dissemination of offspring to the environment. Helminths initiate the IL-25-mediated tuft cell-type 2 innate lymphoid cell (ILC2) circuit that enhances barrier protection of the host, although viable parasites can target and limit this pathway. We used IL-25 alone to create small intestinal adaptation, marked by anatomic and immunologic changes that persisted months after induction.
