Hybrids between HS-donors and betamethasone 17-valerate or triamcinolone acetonide inhibit mast cell degranulation and promote hyperpolarization of bronchial smooth muscle cells.

Eur J Med Chem 2021 May 5;221:113517. Epub 2021 May 5.

Department of Pharmacy, University of Naples «Federico II», Via D. Montesano 49, Naples, Italy. Electronic address:

Glucocorticoids represent the standard gold treatment of inflammation in asthmatic patients. More recently, HS has been described to exert positive effect on this disease. Bearing in mind that an improved pharmacological activity and a reduced toxicity can be obtained through hybridization of different molecules, simultaneously modulating multiple targets, we designed and synthesized novel betamethasone 17-valerate and triamcinolone acetonide hybrids with well-known HS-donor moieties.

Silencing a disintegrin and metalloproteinase‑33 attenuates the proliferation of vascular smooth muscle cells via PI3K/AKT pathway: Implications in the pathogenesis of airway vascular remodeling.

Mol Med Rep 2021 Jul 13;24(1). Epub 2021 May 13.

State Key Laboratory of Pathogenesis, Prevention and Treatment of High Incidence Diseases in Central Asia, Department of Respiratory Medicine, The First Affiliated Hospital of Xinjiang Medical University, Urumqi, Xinjiang Uyghur Autonomous Region 830054, P.R. China.

Accumulating evidence suggests that pulmonary expression of a disintegrin and metalloproteinase‑33 (ADAM33) serves a key role in the pathogenesis of airway remodeling‑related diseases, including asthma. Airway vascular proliferation has been recognized as a key feature of airway remodeling. Our previous study showed that ADAM33 is constitutively expressed in airway vascular smooth muscle cells in patients with asthma, suggesting a potential role of ADAM33 in regulating airway vascular remodeling.

3,4,5‑Trihydroxycinnamic acid exerts anti‑inflammatory effects on TNF‑α/IFN‑γ‑stimulated HaCaT cells.

Mol Med Rep 2021 Jul 13;24(1). Epub 2021 May 13.

Natural Medicine Research Center, Korea Research Institute of Bioscience and Biotechnology (KRIBB), Cheongju, Chungcheongbuk‑do 28116, Republic of Korea.

3,4,5‑Trihydroxycinnamic acid (THCA) exhibits anti‑inflammatory activity in acute or chronic inflammatory disorders, such as acute lung injury and asthma. The present study investigated the anti‑inflammatory activity of THCA in a tumor necrosis factor‑α/interferon‑γ (TI) mixture‑stimulated human keratinocyte cell line. The results of ELISA and reverse transcription‑quantitative PCR revealed that THCA reduced the secretion and mRNA expression levels of interleukin (IL)‑6; IL‑8; thymus and activation‑regulated chemokine; macrophage‑derived chemokine; regulated upon activation, normal T cell expressed and secreted; and monocyte chemoattractant protein‑1 in TI mixture‑stimulated HaCaT cells.

Pleiotropic associations of heterozygosity for the Z allele in the UK Biobank.

ERJ Open Res 2021 Apr 10;7(2). Epub 2021 May 10.

Division of Respiratory Medicine, University of Nottingham, and NIHR Nottingham BRC, NUH NHS Trust, Nottingham, UK.

Homozygosity for the Z allele causes α-antitrypsin deficiency, a rare condition that can cause lung and liver disease. However, the effects of Z allele heterozygosity on nonrespiratory phenotypes, and on lung function in the general population, remain unclear. We conducted a large, population-based study to determine Z allele effects on >2400 phenotypes in the UK Biobank (N=303 353). Read More

Contribution of Satellite-Derived Aerosol Optical Depth PM Bayesian Concentration Surfaces to Respiratory-Cardiovascular Chronic Disease Hospitalizations in Baltimore, Maryland.

Atmosphere (Basel) 2020 18;11(2):209. Epub 2020 Feb 18.

I. M. Systems Group, 5825 University Research Ct, Suite 3250, College Park, MD 20740, USA.

The fine particulate matter baseline (PMB), which includes PM monitor readings with Community Multiscale Air Quality (CMAQ) model predictions, using the Hierarchical Bayesian Model (HBM), is less accurate in rural areas without monitors. To address this issue, an upgraded HBM was used to form four experimental aerosol optical depth (AOD)-PM concentration surfaces. A case-crossover design and conditional logistic regression evaluated the contribution of the AOD-PM surfaces and PMB to four respiratory-cardiovascular hospital events in all 99 12 km CMAQ grids, and in grids with and without ambient air monitors.

Studies of mitochondrial and nuclear DNA released from food allergen-activated neutrophils. Implications for non-IgE food allergy.

Allergy Asthma Proc 2021 May;42(3):e59-e70

Department of Pediatrics and Microbiology-Immunology, Georgetown University Medical Center, Washington, D.C., (USA); and.

Although adverse food reactions are commonly divided into immunoglobulin E (IgE) mediated food allergy (FA), and non-IgE FA, the current literature is providing support for the role of innate immune responses as an important component of non-IgE FA. Using a commercially available leukocyte activation (LA) assay, a recent quantitative study of total extracellular DNA released in cellular supernatants of human peripheral blood mononuclear cells exposed either to positive or negative tested foods demonstrated that leukocytes exposed to foods with positive LA test results showed higher DNA content than those exposed to foods with negative LA test results. In humans, the origin of DNA might be either the nucleus or the mitochondria. Read More
