On the impact of hepatitis C virus and heterologous immunity on alloimmune responses following liver transplantation

American Journal of Transplantation, 2020
Virus‐induced heterologous immunity is considered a barrier to transplantation tolerance. Yet, hepatitis C (HCV)‐infected liver transplant (LT) patients occasionally achieve operational tolerance.

Cellular immunity predominates over humoral immunity after homologous and heterologous mRNA and vector-based COVID-19 vaccine regimens in solid organ transplant recipients

American Journal of Transplantation, 2021
Knowledge on the immunogenicity of vector‐based and mRNA‐vaccines in solid organ transplant recipients is limited. Therefore, SARS‐CoV‐2–specific T cells and antibodies were analyzed in 40 transplant recipients and 70 controls after homologous or ...

Heterologous Ad.26.COV2.S versus homologous BNT162b2/mRNA-1273 as a third dose in solid organ transplant recipients seronegative after two-dose mRNA vaccination

American Journal of Transplantation, 2022
Heterologous vaccination (“mixing platforms”) for the third (D3) dose of SARS‐CoV‐2 vaccine is a potential strategy to improve antibody responses in solid organ transplant recipients (SOTRs), but data are mixed regarding potential differential ...

Acellular Fish Skin for Deep Dermal Traumatic Wounds Management; Introducing a Novel Dressing

Archives of Academic Emergency Medicine, 2023
The optimal therapy for deep wounds is based on the early debridement of necrotic tissue followed by wound coverage to avoid a systemic inflammatory response and optimize scar-free healing. The outcomes are affected by available resources and underlying

Enhanced SARS-CoV-2 Antibody Response After a Third Heterologous Vector Vaccine Ad26COVS1 Dose in mRNA Vaccine-Primed Kidney Transplant Recipients

Transplant International, 2022
Dear Editors,Weandothers have shown that kidney transplant recipients (KTR) exhibit a reduced immune response with a seroconversion (SC) rate < 50% after a regular 2-dose mRNA SARS-CoV-2 vaccination regimen (1, 2).
