Background: Inflammatory myofibroblastic tumor (IMT) of the lung is a rare lung tumor, accounting for 0.7% of all lung tumors. They are usually benign, but can invade surrounding structures, undergo malignant transformation, recur, or even metastasize.
Case Report: We report a 44-year-old adult diabetic male from Saudi Arabia who had been suffering from cough with severe sputum and left shoulder pain for 2 weeks. Chest radiography (X-ray and computed tomography (CT)) revealed the presence of a mass lesion in the left lower upper lobe with central cavitation. The diagnosis of inflammatory myofibroblast lung tumor was confirmed by histological and immunohistochemical examination of the CT guided lung biopsy. The patient was successfully treated with surgical resection of the tumor by left limited thoracotomy with safety margin, and IMT was also documented.
Conclusion: A high degree of suspicion of a solitary pulmonary mass is required for diagnosis and management of an inflammatory myofibroblastic lung tumor. The clinical and radiologic presentation of an inflammatory myofibroblastic tumor is nonspecific and the diagnosis is rarely made before surgical biopsy. Histologic and immunohistochemical examination is usually required to confirm the diagnosis and prevent recurrence.

Immunity suffers a function deficit during aging, and the incidence of cancer is increased in the elderly. However, most cancer models employ young mice, which are poorly representative of adult cancer patients. We have previously reported that Triple-Therapy (TT), involving antigen-presenting-cell activation by vinorelbine and generation of TCF1-stem-cell-like T cells (scTs) by cyclophosphamide significantly improved anti-PD-1 efficacy in anti-PD1-resistant models like Triple-Negative Breast Cancer (TNBC) and Non-Hodgkin's Lymphoma (NHL), due to T-cell-mediated tumor killing.

Chronic kidney disease (CKD) ultimately causes renal fibrosis and end-stage renal disease, thus seriously threatens human health. However, current medications for CKD and fibrosis are inefficient, which is often due to poor targeting capability to renal tubule. In this study, we discover that biomimetic high-density lipoprotein (bHDL) lipid nanoparticles possess excellent targeting ability to injured tubular epithelial cells by kidney injury molecule-1(KIM-1) mediated internalization.

Inflammaging, a state of chronic low-grade inflammation associated with aging, has been linked to the development and progression of various disorders. Cellular senescence, a state of irreversible growth arrest, is another characteristic of aging that contributes to the pathogenesis of cardiovascular pathology. Senescent cells accumulate in tissues over time and secrete many inflammatory mediators, further exacerbating the inflammatory environment.

Intestinal fibrosis, as a late-stage complication of inflammatory bowel disease (IBD), leads to bowel obstruction and requires surgical intervention, significantly lowering the quality of life of affected patients. SAA3, a highly conserved member of the serum amyloid A (SAA) apolipoprotein family in mice, is synthesized primarily as an acute phase reactant in response to infection, inflammation and trauma. An increasing number of evidence suggests that SAA3 exerts a vital role in the fibrotic process, even though the underlying mechanisms are not yet fully comprehended.

Background: Hypertrophic scar (HS) is a severe skin fibrosis. Transplanting stem cells carrying anti-fibrotic cytokine genes, like interferon-gamma (IFN-γ), is a novel therapeutic strategy. Human amniotic epithelial cells (hAECs) are ideal seed cells and gene vectors.
