Autoimmune Regulator (AIRE) is required in female mice for optimal embryonic development and implantation1.

Biol Reprod 2019 Feb 16. Epub 2019 Feb 16.

Dept. Pathobiology & Diagnostic Investigation, and.

Autoimmune Regulator (AIRE) regulates central immune tolerance by inducing expression of tissue-restricted antigens in thymic medullary epithelial cells, thereby ensuring elimination of autoreactive T cells. Aire mutations in humans and targeted Aire deletion in mice results in multi-organ autoimmune disease, known in humans as Autoimmune Polyglandular Syndrome Type 1 (APS-1). APS-1 is characterized by presence of adrenal insufficiency, chronic mucosal candidiasis, and/or hypoparathyroidism. Read More

Lessons from primary immunodeficiencies: Autoimmune regulator and autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy.

Immunol Rev 2019 Jan;287(1):103-120

Fungal Pathogenesis Section, Laboratory of Clinical Immunology and Microbiology, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, Maryland.

The discovery of the autoimmune regulator (AIRE) protein and the delineation of its critical contributions in the establishment of central immune tolerance has significantly expanded our understanding of the immunological mechanisms that protect from the development of autoimmune disease. The parallel identification and characterization of patient cohorts with the monogenic disorder autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED), which is typically caused by biallelic AIRE mutations, has underscored the critical contribution of AIRE in fungal immune surveillance at mucosal surfaces and in prevention of multiorgan autoimmunity in humans. In this review, we synthesize the current clinical, genetic, molecular and immunological knowledge derived from basic studies in Aire-deficient animals and from APECED patient cohorts. Read More

Department of Biological Sciences, School of Dental Medicine, Case Western Reserve University, Cleveland, OH, United States.

Interactions between mucosal tissues and commensal microbes control appropriate host immune responses and inflammation, but very little is known about these interactions. Here we show that the depletion of resident bacteria using antibiotics (Abx) causes oral and gut immunopathology during oropharyngeal candidiasis (OPC) infection. Antibiotic treatment causes reduction in the frequency of Foxp3+ regulatory cells (T) and IL-17A producers, with a concomitant increase in oral tissue pathology. Read More

Loss of Upc2p-Inducible Transcription Is Sufficient To Confer Niche-Specific Azole Resistance without Compromising Candida albicans Pathogenicity.

MBio 2018 05 22;9(3). Epub 2018 May 22.

Department of Clinical Pharmacy and Translational Science, College of Pharmacy, University of Tennessee Health Sciences Center, Memphis, Tennessee, USA

Inactivation of sterol Δ-desaturase (Erg3p) in the prevalent fungal pathogen is one of several mechanisms that can confer resistance to the azole antifungal drugs. However, loss of Erg3p activity is also associated with deficiencies in stress tolerance, invasive hyphal growth, and attenuated virulence in a mouse model of disseminated infection. This may explain why relatively few -deficient strains have been reported among azole-resistant clinical isolates. Read More

Langerin+ DCs regulate innate IL-17 production in the oral mucosa during Candida albicans-mediated infection.

PLoS Pathog 2018 05 21;14(5):e1007069. Epub 2018 May 21.

Section of Immunology, Vetsuisse Faculty, University of Zürich, Zürich, Switzerland.

The opportunistic fungal pathogen Candida albicans frequently causes diseases such as oropharyngeal candidiasis (OPC) in immunocompromised individuals. Although it is well appreciated that the cytokine IL-17 is crucial for protective immunity against OPC, the cellular source and the regulation of this cytokine during infection are still a matter of debate. Here, we directly visualized IL-17 production in the tongue of experimentally infected mice, thereby demonstrating that this key cytokine is expressed by three complementary subsets of CD90+ leukocytes: RAG-dependent αβ and γδ T cells, as well as RAG-independent ILCs.

Role of protein phosphomannosylation in the Candida tropicalis-macrophage interaction.

FEMS Yeast Res 2018 08;18(5)

Departamento de Biología, Universidad de Guanajuato, Noria Alta s/n, col. Noria Alta, C.P. 36050, Guanajuato, Gto., México.

Candida tropicalis is an opportunistic fungal pathogen responsible for mucosal and systemic infections. The cell wall is the initial contact point between a fungal cell and the host immune system, and mannoproteins are important components that play key roles when interacting with host cells. In Candida albicans, mannans are modified by mannosyl-phosphate moieties, named phosphomannans, which can work as molecular scaffolds to synthesize β1,2-mannooligosaccharides, and MNN4 is a positive regulator of the phosphomannosylation pathway.

Fungal infections are a major problem for a growing number of mostly immunocompromised patients. Candida albicans is an important human fungal pathogen causing mucosal and deep tissue infections, of which the majority are associated with biofilm formation on medical implants. Animal models that are currently in use to test antifungal drugs are limited to ex vivo analyses, requiring host sacrifice that excludes longitudinal monitoring of dynamic processes during biofilm formation in the live host.
