Clusterization of patients with idiopathic pulmonary fibrosis with chemokine receptors: a possible role in the diagnostic work-up of idiopathic pulmonary fibrosis?

Sarcoidosis Vasc Diffuse Lung Dis 2018 28;35(1):35-43. Epub 2018 Apr 28.

Allergy and Immunology Unit, Istituti Clinici Scientifici Maugeri IRCCS, Pavia, Italy.

Idiopathic pulmonary fibrosis (IPF) is a chronic and irreversible interstitial lung disease whose diagnosis often requires surgical lung biopsies (SLB) in cases without consistent radiological findings. We previously published that the expression of the chemokine receptors CXCR3 and CCR4 on T cells is significantly different in bronchoalveolar lavage (BAL) of IPF patients from other interstitial lung diseases. The aim of the study was to evaluate cut-off values of CXCR3 and CCR4 receptors expressed on bronchoalveolar lavage (BAL) and peripheral blood (PB) T cells useful for a differential diagnosis.

Focus on Receptors for Coronaviruses with Special Reference to Angiotensin-converting Enzyme 2 as a Potential Drug Target - A Perspective.

Endocr Metab Immune Disord Drug Targets 2020 Apr 27. Epub 2020 Apr 27.

Department of Basic Medical Sciences, Neuroscience and Sensory Organs, University of Bari, School of Medicine, Bari. Italy.

Coronaviruses (CoVs) possess an enveloped, single, positive-stranded RNA genome which encodes for four membrane proteins, namely spike (S), envelope (E), membrane (M) and nucleocapsid (N) proteins 3-5 [1]. With regard to pathogenicity, S proteins are essential for viral entry into host cells [2, 3]. SARS-CoV binds to the angiotensin-converting enzyme (ACE)2 which is present on nonimmune cells, such as respiratory and intestinal epithelial cells, endothelial cells, kidney cells (renal tubules) and cerebral neurons and immune cells, such as alveolar monocytes/macrophages [4-6].

Traumatic ulcerative granuloma with stromal eosinophilia - clinical case report, literature review, and differential diagnosis.

World J Surg Oncol 2019 Nov 9;17(1):184. Epub 2019 Nov 9.

Department of Oral and Craniomaxillofacial Surgery, University Hospital Basel, Spitalstrasse 21, CH-4031, Basel, Switzerland.

Background: Traumatic ulcerative granuloma with stromal eosinophilia (TUGSE) is a rare self-limiting condition of the oral mucosa. The lesion manifests as an isolated ulcer that can be either asymptomatic or associated with mild to severe pain, and in most cases, it affects the tongue. TUGSE lesions may mimic malignancy such as squamous cell carcinoma, CD30 positive lymphoproliferative disorder, or infectious diseases such as primary syphilis, tuberculosis, or Epstein-Barr virus mucocutaneous ulcer.

The Levels of Interferon-gamma Release as a Biomarker for Non-small-cell Lung Cancer Patients Receiving Immune Checkpoint Inhibitors.

Anticancer Res 2019 Nov;39(11):6231-6240

Department of Allergy, Osaka Habikino Medical Center, Osaka, Japan.

Background/aim: The present study aimed to prospectively examine the usefulness of interferon-gamma (IFN-γ) release (IGR) as a biomarker in non-small-cell lung cancer patients receiving immune checkpoint inhibitor treatment (ICI-Tx).

Patients And Methods: IGR was measured using enzyme-linked immunosorbent assay at four time points: within 14 days before ICI-Tx (T1), and 8±3 (T2), 22±7 (T3), and 43±7 (T4) days after ICI-Tx.

Results: Twenty-nine patients were divided into three groups based on IFN-γ levels in the IGR-positive control: Group-1 (n=8) with <10 IU/ml at T1, Group-2 (n=12) with a decrease in IFN-γ levels to <10 IU/ml at T3 and/or T4, and Group-3 (n=9) without changes in IFN-γ levels. Read More

Connective tissue diseases (CTDs) can affect all compartments of the lungs, including airways, alveoli, interstitium, vessels, and pleura. CTD-associated lung diseases (CTD-LDs) may present as diffuse lung disease or as focal lesions, and there is significant heterogeneity between the individual CTDs in their clinical and pathological manifestations. CTD-LDs may presage the clinical diagnosis a primary CTD, or it may develop in the context of an established CTD diagnosis. Read More

Myeloid HIF-1α regulates pulmonary inflammation during experimental Mycobacterium tuberculosis infection.

Immunology 2020 01 10;159(1):121-129. Epub 2019 Nov 10.

Life and Health Sciences Research Institute (ICVS), School of Medicine, University of Minho, Braga, Portugal.

The transcription factor hypoxia-inducible factor-1 alpha (HIF-1α) is a key regulator of the response and function of myeloid cells in hypoxic and inflammatory microenvironments. To define the role of HIF-1α in tuberculosis, the progression of aerosol Mycobacterium tuberculosis infection was analysed in mice deficient in HIF-1α in the myeloid lineage (mHIF-1α ). We show that myeloid HIF-1α is not required for the containment of the infection, as both wild-type (WT) and mHIF-1α mice mounted normal Th1 responses and maintained control of bacterial growth throughout infection.

BRAF V600E and Pten deletion in mice produces a histiocytic disorder with features of Langerhans cell histiocytosis.

PLoS One 2019 17;14(9):e0222400. Epub 2019 Sep 17.

Department of Medical Oncology, Dana-Farber Cancer Institute, Harvard Medical School, Boston, MA, United States of America.

Langerhans cell histiocytosis (LCH) is characterized by the accumulation of Langerin (CD207)-expressing histiocytes. Mutational activation of mitogen-activated protein kinase pathway genes, in particular BRAF, drives most cases. To test whether activated BRAF is sufficient for the development of LCH, we engineered mice to express BRAF V600E under the control of the human Langerin promoter. Read More
