Oropharyngeal Candidiasis in HIV Infection: Analysis of Impaired Mucosal Immune Response to Candida albicans in Mice Expressing the HIV-1 Transgene
IL-17-producing Th17 cells are of critical importance in host defense against oropharyngeal candidiasis (OPC). Speculation about defective Th17 responses to oral C. albicans infection in the context of HIV infection prompted an investigation of innate and adaptive immune responses to Candida albicans in transgenic mice expressing the genome of HIV-1 in immune cells and displaying an AIDS-like d...
متن کاملTrafficking of Candida albicans through oral epithelial endocytic compartments.
Oral epithelial cells are the first cells that interact with C. albicans during the establishment of oropharyngeal candidiasis. Following initial adhesion, C. albicans invades oral epithelial cells by inducing its own endocytosis and gains access to epithelial vacuolar compartments. Epithelial endocytic pathways are key innate immune mechanisms in host defense. We examined the trafficking of C....
متن کاملHost defense against oropharyngeal and vaginal candidiasis: Site-specific differences.
Mucosal candidiasis is extremely common in immunocompromised patients. However, the prevalence of site-specific infection (i.e., oropharyngeal, vaginal, and esophageal candidiasis) can be quite variable depending on the immune status of the host. While vulvovaginal candidiasis is common in normal healthy women, oropharyngeal and esophageal candidiasis are more frequently encountered under immun...
متن کاملSalivary mucins in host defense and disease prevention
Mucus forms a protective coating on wet epithelial surfaces throughout the body that houses the microbiota and plays a key role in host defense. Mucins, the primary structural components of mucus that creates its viscoelastic properties, are critical components of the gel layer that protect against invading pathogens. Altered mucin production has been implicated in diseases such as ulcerative c...
متن کاملA Clinician’s Guide to the Diagnosis and Treatment of Candidiasis in Patients with Psoriasis
Many of the molecular pathways associated with psoriasis pathogenesis are also involved in host defense mechanisms that protect against common pathogens. Candida can stimulate the production of cytokines that trigger or exacerbate psoriasis, and many systemic psoriasis treatments may put patients at increased risk for developing oral, cutaneous, and genitourinary candidiasis. Therefore, dermato...
