A 39 years old man with a long-standing disseminated dermatophytosis even with several antifungal treatments is presented. From lesions, Trichophyton rubrum var. typical downy, T. tonsurans and Candida albicans were isolated and showed sensivity to azolic compounds in vitro. The phagocytic activity in vitro compared with normal control was depressed. Treatment with itraconazole and immunomodulation using a bacterial antigen was indicated. During the last two years the patient has been clinical and mycologically healthy, and his phagocytosis activity has become normal. In patients with chronic and relapsing dermatophytosis, the immune response evaluation is recommended, and immunomodulation could be useful as a rational measure in patients with a particular immunodeficiency.

Among the diverse fungal opportunistic pathogens, garners significant attention due to its wide range of infections and high frequency of occurrence. The emergence of resistance and the limited number of antifungals drives the need to develop novel antifungal drugs. Although the natural product baicalin has been shown to trigger apoptosis in in previous experiments, its influence on cell wall (CW) structure along with immune recognition remains elusive.

Unlabelled: Myeloid phagocytes are essential for antifungal immunity against pulmonary and systemic infections. However, the molecular mechanisms underlying fungal clearance by phagocytes remain incompletely understood. In this study, we investigated the role of Perforin-2 () in antifungal immunity.

Candida glabrata is an opportunistic human pathogen, capable of causing severe systemic infections that are often resistant to standard antifungal treatments. To understand the importance of protein SUMOylation in the physiology and pathogenesis of C. glabrata, we earlier identified the components of SUMOylation pathway and demonstrated that the deSUMOylase CgUlp2 is essential for pathogenesis.

Candida albicans is the most common human fungal pathogen, causing diseases ranging from local to life-threating systemic infections. Tyrosine kinase 2 (TYK2), a crucial mediator in several cytokine signaling pathways, has been associated with protective functions in various microbial infections. However, its specific contribution in the immune response to fungal infections has remained elusive.

Background: Idiopathic pulmonary fibrosis (IPF) stands as a significant contributor to global mortality rates. Presently, there exists a dearth of effective anti-fibrotic treatments for this condition. While itraconazole (ITR) has exhibited potential in mitigating pulmonary fibrosis, its oral administration is hampered by unfavorable pharmacokinetics, which elevate the risk of adverse reactions, thus limiting its clinical utility.
