The trend of phylogenetic and epitope variations of SARS-CoV-2 Omicron sub-lineages in Iran by Mehdi Shabani, Ahmad Nejati, Jila Yavarian, Jila Yavarian, Kaveh Sadeghi, Sevrin Zadheidar, Akram Sadat Ahmadi, Monire Ghadirali, Arghavan Zebardast, Adel Abedi, Mohammad Hossein Najmi, Nazanin-Zahra Shafiei-Jandaghi, Talat Mokhtari-Azad

“…CD4+), protein (higher for non-spike vs. spike), and clades (higher for 21L, 22F, 23B, 23H, 23D, and 24B vs. 24A and 24C).ConclusionHerein, the increased conservation of CD8+ epitopes compared to CD4+ and B cell epitopes is probably attributable to the shorter length of the peptides associated with CD8+ epitopes. The high rate of T-cell epitopes conservation in non-spike proteins among different sub-lineages of the Omicron in this study highlighted the importance of cell-mediated immunity and suggested that non-spike proteins might be more attractive targets for future SARS-CoV-2 vaccines.…”

“…Due to the inherent nuclease‐instability and negative charge of mRNA, delivery systems are developed to protect the mRNA from degradation and facilitate its crossing cell membrane to express functional proteins or peptides in the cytoplasm. However, the deficiency in transfection efficiency and targeted biological distribution are still the major challenges for the mRNA delivery systems. …”
