Pulmonary fibrosis is characterized by damage to the epithelial cells and alveolar-capillary basement membrane. The increased expression levels of transforming growth factor β (TGF-β) and TGF-β-receptor-1 induced differentiation of lung fibroblasts to myofibroblasts, an alarming sign and considered the hallmark event development of pulmonary fibrosis. In the current study, the stability of phytochemicals of and as inhibitors of transforming growth factor β RI (TGF-β RI) were evaluated using molecular docking and molecular dynamics studies. A total of 108 and 16 constituents were screened against TGF-β RI as the target. Further, their ADMET properties were evaluated using the pkCSM online server. The compounds tembetarine, magnoflorine from , and 2-(Hydroxymethyl) anthraquinone and quercetin in showed significant binding affinities bonding interactions with the target, TGF-β RI, and the study was compared with the known inhibitors from the literature. The MD simulations study also supported that the selected compounds show a close affinity with the binding site and maintained stable behavior throughout the simulation time. The pharmacophore feature analysis of the selected compounds and inhibitors were analyzed using the pharmagist web server, and the common features like H-bond donor and aromatic ring were mapped.Communicated by Ramaswamy H.

Objective: This studied investigated whether changes in circulating biomarkers predict progressive pulmonary fibrosis (PFF) in patients with systemic sclerosis-associated interstitial lung disease (ILD) receiving treatment.
Method: Participants of Scleroderma Lung Study (SLS) II, which compared mycophenolate (MMF) versus cyclophosphamide (CYC) for SSc-ILD, who had blood samples at baseline and 12-months were included. Levels for C-reactive protein (CRP), interleukin (IL)-6, chemokine ligand 4 (CXCL4), chemokine ligand 18 (CCL18) and Krebs von den Lungen 6 (KL-6) were measured, and a logistic regression model evaluated relationships between changes in these biomarkers and the development of PPF by 24 months.

In the current study, we dosed Didecyldimethylammonium chloride (DDAC) in mice by pharyngeal aspiration for 28 days or 90 days (weekly) and tried to elucidate the relationship between lamellar body formation and the lesions. When exposed for 28 days (0, 5, 10, 50, and 100 μg/head), all the mice in the 50 and 100 μg/head groups died since Day 2 after the third dosing (Day 16 after the first dosing). Edema, necrosis of bronchiolar and alveolar epithelium, and fibrinous exudate were observed in the lungs of all the dead mice, and chronic inflammatory lesions were observed in the lung tissues of alive mice.

Aim: Idiopathic pulmonary fibrosis (IPF) is a debilitating and fatal lung disease. Changes in body composition potentially correlate with outcomes in patients with IPF.
Materials And Methods: Patients with IPF on antifibrotic treatment attending a single institution were identified and retrospectively evaluated (n=84).

Aims: COVID-19, caused by the SARS-CoV-2 virus, can lead to serious lung conditions, notably interstitial pulmonary fibrosis.
Main Methods: Our study tracked the progression of fibrosis markers in serial bronchoalveolar lavage (BAL) measurements collected from 16 COVID-19 patients at 1, 3, and 6 months post-infection. Additionally, BAL samples from 10 healthy control subjects were included.

Purpose: To develop and validate the patient-reported outcome scale for idiopathic pulmonary fibrosis (IPF-PRO) to provide a reliable and scientific measure for clinical trials on idiopathic pulmonary fibrosis (IPF).
Methods: We analyzed the relevant literature and medical records and conducted interviews and panel discussions to develop the conceptual framework and generate the item pool. We subjected the collected items to removal, mergence, or modification to form the initial scale through a qualitative review by experts and patients.
