Objectives: Tinea capitis remains a common fungal infection in children worldwide. Species identification is critical for determining the source of infection and reducing transmission. In conventional methods, macro- and microscopic analysis is time-consuming and results in slow fungal growth or low specificity.

Dermatophyte biofilms frequently count for inadequate responses and resistance to standard antifungal treatments, resulting in refractory chronic onychomycosis infection. Although antimicrobial photodynamic therapy (aPDT) has clinically proven to exert significant antifungal effects or even capable of eradicating dermatophyte biofilms, considerably less is known about the molecular mechanisms underlying aPDT and the potential dysregulation of signaling networks that could antagonize its action. The aim of this study is to elucidate the molecular mechanisms underlining aPDT combat against dermatophyte biofilm in recalcitrant onychomycosis and to decipher the potential detoxification processes elicited by aPDT, facilitating the development of more effective photodynamic interventions.

Article Synopsis
  • Psoriatic patients often have onychomycosis (OM), but evaluating it in them is complicated due to possible differences from non-psoriatic cases.
  • This study examined the dermoscopic features of toenail OM in 183 psoriatic patients compared to 232 non-psoriatic patients from 2020 to 2023, revealing significant differences in appearance.
  • Results showed psoriatic toenail OM had more pitting and periungual telangiectasis, while non-psoriatic cases had features like nail spikes and yellow structureless areas, indicating distinct characteristics between the two groups.

The WHO established the first fungal priority pathogens list (FPPL) in October 2022 to focus on and promote further research and policy interventions to strengthen the global response to fungal infections and antifungal resistance. The FPPL and its formulation process provide new significant insights for managing pathogenic fungi and invasive fungal disease (IFD) in China, necessitating the following key actions: Strengthen public health interventions for IFD. Further, it improves the ability of laboratory testing and clinical supervision for IFD and pathogenic fungi.

At present, the public health risks caused by pathogenic fungi are greater in China and have attracted great attention from disease control departments. Due to the difficulty in diagnosing fungal infections, the public health risk of pathogenic fungi is currently hidden in the unexplained pneumonia/encephalitis/fever syndrome and is not effectively appreciated. From the public health perspective, the mainly focused fungal pathogens include highly pathogenic fungi (including dimorphic fungi and dematiaceous fungi), pathogenic fungi that cause regional aggregation infections, and drug-resistant pathogenic fungi.

Dermatophytosis is a common superficial infection caused by dermatophytes, a group of pathogenic keratinophilic fungi. Apart from invasion against skin barrier, host immune responses to dermatophytes could also lead to pathologic inflammation and tissue damage to some extent. Therefore, it is of great help to understand the pathogenesis of dermatophytes, including fungal virulence factors and anti-pathogen immune responses.

Article Synopsis
  • - The frequent renaming of medically significant fungi is complicating the work of clinical labs and healthcare providers, highlighting the need for better communication and resources in this area.
  • - Different factors drive name changes at the species and genus levels, prompting the authors to suggest maintaining larger genera and providing diagnostic markers for new classifications to help simplify identification.
  • - The authors call for an open-access online database to track these changes, recommending a committee to regularly review new names so that clinicians can access consistent and validated information about fungal species.

Genomes of strains of the zoophilic dermatophyte from invasive (disseminated and subcutaneous) and noninvasive (tinea capitis) infections were compared. Especially the disseminated strain showed significant syntenic rearrangements, including multiple translocations and inversions, and numerous SNPs and Indels in comparison to the noninvasive strain. In transcriptome analysis, both invasive strains were enriched for GO pathways related to components of the membrane, iron binding and heme binding, which possibly enables them to invade deeper into dermis and blood vessels.

Infections by dematiaceous fungi especially phaeohyphomycosis are an emerging group of infectious diseases worldwide with a variety of clinical presentations. The mouse model is a useful tool for studying phaeohyphomycosis, which can mimic dematiaceous fungal infections in humans. Our laboratory has successfully constructed a mouse model of subcutaneous phaeohyphomycosis and found significant phenotypic differences between Card9 knockout and wild-type mice, mirroring the increased susceptibility to this infection observed in CARD9-deficient humans.
