Adoptive transfer of ex vivo expanded SARS‐CoV‐2‐specific cytotoxic lymphocytes: A viable strategy for COVID‐19 immunosuppressed patients?
2021
Cellular and humoral response to acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infections is on focus of research. We evaluate herein the feasibility of expanding virus‐specific T cells (VST) against SARS‐CoV‐2 ex vivo through a standard protocol proven effective for other viruses. The experiment was performed in three different donors' scenarios: (a) SARS‐CoV‐2 asymptomatic infection/negative serology, (b) SARS‐CoV‐2 symptomatic infection/positive serology, and (c) no history of SARS‐CoV‐2 infection/negative serology. We were able to obtain an expanded VST product from donors 1 and 2 (1.6x and 1.8x increase of baseline VST count, respectively) consisting in CD3 + cells (80.3% and 6…
Cellular Uptake of siRNA-Loaded Nanocarriers to Knockdown PD-L1: Strategies to Improve T-cell Functions
2020
T-cells are a type of lymphocyte (a subtype of white blood cells) that play a central role in cell-mediated immunity. Currently, adoptive T-cell immunotherapy is being developed to destroy cancer cells. In this therapy, T-cells are harvested from a patient&rsquo
