Infection in a C3HeB/FeJ Mouse Model.

Front Microbiol 2019 3;10:693. Epub 2019 Apr 3.

Mycobacteria Research Laboratories, Department of Microbiology, Immunology and Pathology, Colorado State University, Fort Collins, CO, United States.

Infections caused by complex (MAC) species are increasing worldwide, resulting in a serious public health problem. Patients with MAC lung disease face an arduous journey of a prolonged multidrug regimen that is often poorly tolerated and associated with relatively poor outcome. Identification of new animal models that demonstrate a similar pulmonary pathology as humans infected with MAC has the potential to significantly advance our understanding of nontuberculosis mycobacteria (NTM) pathogenesis as well as provide a tractable model for screening candidate compounds for therapy.

Expression of CD34 and CD31 in Central and Peripheral Giant Cell Granulomas.

J Dent (Shiraz) 2019 Mar;20(1):10-15

Dept. of Oral and Maxillofacial Pathology, Dental Branch of Tehran, Islamic Azad University, Tehran, Iran.

Statement Of The Problem: There are some differences between clinical features of central giant cell granulomas (CGCGs) and peripheral giant cell granulomas (CGCGs) despite their same microscopic features. The possible role of angiogenesis in this issue is still a matter of debate.

Purpose: The aim of the present study was to compare microvessel density (MVD) between CGCGs and PGCGs of the oral cavity using CD31 and CD34. Read More

In Vitro Granuloma Models of Tuberculosis: Potential and Challenges.

J Infect Dis 2019 Mar 31. Epub 2019 Mar 31.

Texas Biomedical Research Institute, San Antonio, Texas.

Despite intensive research efforts, several fundamental disease processes for tuberculosis (TB) remain poorly understood. A central enigma is that host immunity is necessary to control disease yet promotes transmission by causing lung immunopathology. Our inability to distinguish these processes makes it challenging to design rational novel interventions. Read More

Chronic granulomatous pneumonia and lung rupture secondary to aspiration of activated charcoal in a French Bulldog.

Vet Clin Pathol 2019 Mar;48(1):67-70

Department of Pathology, University of Georgia, Athens, Georgia.

A 4-year-old, spayed female French Bulldog was presented for respiratory distress and suspected aspiration pneumonia after oral administration of activated charcoal for possible ingestion of a suspected toxic dose of trazodone. The patient had a moderate volume of pleural effusion, which contained free and intracellular black particulate matter consistent with charcoal. Due to presumed charcoal aspiration with subsequent lung rupture, the right middle and right caudal lung lobes were surgically removed. Read More

Myeloid cell TNFR1 signaling dependent liver injury and inflammation upon BCG infection.

Sci Rep 2019 Mar 28;9(1):5297. Epub 2019 Mar 28.

Department of Pathology and Immunology, Centre Medical Universitaire (CMU), Faculty of Medicine, University of Geneva, Geneva, 1211, Switzerland.

TNF plays a critical role in mononuclear cell recruitment during acute Bacillus Calmette-Guérin (BCG) infection leading to an effective immune response with granuloma formation, but may also cause tissue injury mediated by TNFR1 or TNFR2. Here we investigated the role of myeloid and T cell specific TNFR1 and R2 expression, and show that absence of TNFR1 in myeloid cells attenuated liver granuloma formation and liver injury in response to acute BCG infection, while TNFR2 expressed in myeloid cells contributed only to liver injury. TNFR1 was the main receptor controlling cytokine production by liver mononuclear cells after antigenic specific response, modified CD4/CD8 ratio and NK, NKT and regulatory T cell recruitment.

Foreign-Body Granulomata Caused by Injected Permanent Filler Masquerading as Cutaneous Sarcoidosis.

Ophthalmic Plast Reconstr Surg 2019 Mar 26. Epub 2019 Mar 26.

Department of Ophthalmology, UT Southwestern Medical Center.

Foreign-body granuloma formation following filler injections is most commonly seen with permanent fillers; these reactions can occur years following the injections and often require either an intralesional steroid injection or surgical excision. The authors present a case of a 75-year-old woman with a history of systemic sarcoidosis previously treated with numerous immunosuppressive medications who was examined for bilateral infraorbital nodules and swelling that were unresponsive to treatment. She underwent a bilateral anterior orbitotomy through a transconjunctival approach with mass excision. Read More

Recruitment of hepatic macrophages from monocytes is independent of IL-4Rα but is associated with ablation of resident macrophages in schistosomiasis.

Eur J Immunol 2019 Mar 28. Epub 2019 Mar 28.

Immunology-Vaccinology, Department of Infectious and Parasitic Diseases, Faculty of Veterinary Medicine - FARAH, University of Liège, Liège, Belgium.

Alternatively-activated Mφs (AAMφ) accumulate in hepatic granulomas during schistosomiasis and have been suggested to originate in the bone marrow. What is less understood is how these Mφ responses are regulated after S. mansoni infection. Read More
