Some studies have found that vinorelbine protects against cisplatin-induced acute kidney injury (AKI) by activating Nrf2/HO-1 signaling pathway and hindering TLR4-IFN-γ-CD44 cell inflammatory cascade when investigating the molecular mechanism of renal protection against nephrotoxicity (El-Sayed et al., 2021). Here, CD44 is linked to acute kidney injury.
