The evolution of drug resistance in fungal pathogens compromises the efficacy of the limited number of antifungal drugs. Drug combinations have emerged as a powerful strategy to enhance antifungal efficacy and abrogate drug resistance, but the impact on the evolution of drug resistance remains largely unexplored. Targeting the molecular chaperone Hsp90 or its downstream effector, the protein ph...

Immunosuppression for solid organ transplantation increases lymphoproliferative disease risk. While central nervous system (CNS) involvement is more rare, we noticed an increase in primary CNS (PCNS) disease. To investigate a potential association with the immunosuppressive regimen we identified all post-transplant lymphoproliferative disease (PTLD) cases diagnosed over a 28-year period at our ...

Apoptosis plays a central role in shaping the repertoire of circulating mature B lymphocytes, but the underlying molecular mechanisms regulating B cell fate are not well understood. Human B104 B lymphoma cells undergo apoptosis after surface Ig (sIg)M, but not sIgD, ligation; sIgM-mediated apoptosis of B104 cells apparently requires new gene transcription because actinomycin D can inhibit the a...

Cryptococcus neoformans is an opportunistic fungal pathogen that causes life-threatening infections of the central nervous system. Existing therapies include amphotericin B, fluconazole, and flucytosine, which are limited by toxic side effects and the emergence of drug resistance. We recently demonstrated that the protein phosphatase calcineurin is required for growth at 37 degrees C and virule...

Vitiligo is an acquired, chronic condition characterised by depigmentation of the epidermis or destruction/loss melanin. Skin cells (melanocytes) are responsible for producing melanin, substance that gives pigmentation to skin. This review aims provide a comprehensive overview current state knowledge about vitiligo. Although there no specific ethnic group, gender, skin type more prone vitiligo ...

The present study was undertaken to examine the physical and physiological interaction of protein phosphatase 2B, calcineurin, with the ryanodine receptor (RyR) in rat cardiac tissue and neonatal cardiomyocytes. The presence of calcineurin, the RyR and FK506-binding protein (FKBP)12.6 in rat cardiac sarcoplasmic reticulum (SR) was identified by Western blot analysis. The possible interactions b...
