Engineering immunosuppressive drug-resistant armored (IDRA) SARS-CoV-2 T cells for cell therapy
Cell Mol Immunol. 2023 Sep 5. doi: 10.1038/s41423-023-01080-3. Online ahead of print.ABSTRACTSolid organ transplant (SOT) recipients receive immunosuppressive drugs (ISDs) and are susceptible to developing severe COVID-19. Here, we analyze the Spike-specific T-cell response after 3 doses of mRNA vaccine in a group of SOT patients (n = 136) treated with different ISDs. We demonstrate that a combination of a calcineurin inhibitor (CNI), mycophenolate mofetil (MMF), and prednisone (Pred) treatment regimen strongly suppressed the mRNA vaccine-induced Spike-specific cellular response. Such defects have clinical consequences bec...

Immune responses and safety of COVID-19 vaccination in atypical hemolytic uremic syndrome patients in Taiwan
Vaccine. 2023 Aug 25:S0264-410X(23)00952-0. doi: 10.1016/j.vaccine.2023.08.020. Online ahead of print.ABSTRACTAtypical hemolytic uremic syndrome is a rare, life-threatening disorder which can be triggered by COVID 19 infection and COVID 19 vaccination then induce multiple organ failure. Our study is the first to evaluate immune responses to COVID-19 vaccination and safety in a cohort of patients in a local single-center study in Taiwan.. Results indicate that vaccines effectively shield aHUS patients from severe COVID-19 complications without significant safety concerns. A double booster dose for the third vaccine is essen...

Identification of neutralizing epitopes on the D/A domain of the E2 glycoprotein of classical swine fever virus
Virus Res. 2023 Aug 24:199209. doi: 10.1016/j.virusres.2023.199209. Online ahead of print.ABSTRACTClassical swine fever virus (CSFV) shares high antigenic homology with other members of the genus Pestivirus. Because several pestivirus species can also infect swine, eliciting cross-reactive antibodies, it is important to define CSFV-specific epitopes for the differential diagnosis of classical swine fever (CSF) by serology. For this purpose, epitope mapping of seven monoclonal antibodies (mAbs), recognizing sites on the D/A domain of glycoprotein E2, was performed using recombinant expressed antigenic domains and mutants of...
