A SARS-CoV-2-specific CAR-T-cell model identifies felodipine, fasudil, imatinib, and caspofungin as potential treatments for lethal COVID-19
Cell Mol Immunol. 2023 Mar 2:1-14. doi: 10.1038/s41423-023-00985-3. Online ahead of print.ABSTRACTSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-induced cytokine storm is closely associated with coronavirus disease 2019 (COVID-19) severity and lethality. However, drugs that are effective against inflammation to treat lethal COVID-19 are still urgently needed. Here, we constructed a SARS-CoV-2 spike protein-specific CAR, and human T cells infected with this CAR (SARS-CoV-2-S CAR-T) and stimulated with spike protein mimicked the T-cell responses seen in COVID-19 patients, causing cytokine storm and displaying a...

AFM evaluation of a humanized recombinant antibody affecting < em > C. auris < /em > cell wall and stability
RSC Adv. 2023 Feb 20;13(9):6130-6142. doi: 10.1039/d2ra07217c. eCollection 2023 Feb 14.ABSTRACTFungal infections are increasingly impacting on the health of the population and particularly on subjects with a compromised immune system. The resistance phenomenon and the rise of new species carrying sometimes intrinsic and multi-drug resistance to the most commonly used antifungal drugs are greatly concerning healthcare organizations. As a result of this situation, there is growing interest in the development of therapeutic agents against pathogenic fungi. In particular, the Candida genus is responsible for severe life-threat...

Viruses, Vol. 15, Pages 452: Antiviral Activity of Micafungin and Its Derivatives against SARS-CoV-2 RNA Replication
In this study, we focused on micafungin and its derivatives and analyzed their antiviral activities against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The micafungin derivatives Mi-2 and Mi-5 showed higher antiviral activity than micafungin, with 50% maximal inhibitory concentration (IC50) of 5.25 and 6.51 &micro;M, respectively (3.8 to 4.7-fold stronger than micafungin) and 50% cytotoxic concentration (CC50) of &gt;64 &micro;M in VeroE6/TMPRSS2 cells. This high anti-SARS-CoV-2 activity was also conserved in human lung epithelial cell-derived Calu-3 cells. Micafungin, Mi-2, and Mi...

A six-year hospital-based surveillance study on burden of esophageal candidiasis in Gangtok, Sikkim
CONCLUSION: Upper gastrointestinal symptoms even in non-immunocompromised patients need to be screened by endoscopy to rule out esophageal candidiasis. With the emergence of drug resistant non albicans Candida species diagnostic testing laboratories should include Candida species identification and antifungal susceptibility testing facility to provide effective patient care.PMID:36721503 | PMC:PMC9867645 | DOI:10.18502/ijm.v14i4.10247 (Source: Iranian Journal of Microbiology)

Saprochaete clavata invasive infection: characterization, antifungal susceptibility, and biofilm evaluation of a rare yeast isolated in Brazil
The objective of this study was to describe a new case of severe S. clavata infection in a patient diagnosed at a referral children's hospital in Brazil, including antifungal minimal inhibitory concentration, S. clavata biofilm characterization, and molecular characterization. The S. clavata isolated from an immunocompromised 11-year-old male patient was characterized using MALDI-TOF, Gram staining, scanning electron microscopy (SEM), and next generation sequencing (NGS) of genomic DNA. Biofilm production was also evaluated in parallel with determining minimal inhibitory concentration (MIC) and biofilm sensitivity to antif...
