“…The intercellular structures that support direct transfer are tunnelling nanotubes (TNTs), which are membranous protrusions hanging over the substrate and connecting two adjacent cells. 11 Likewise, RP conjugates were colocalized with TNT-derived F-actin (Figure 3G) and the TNT-derived plasma membrane (Figure 3H) between donor and acceptor cells. The spatial correlation between RP conjugates and tubulin, another component of TNTs, was weak (Figure S5).…”

A selective tumor-penetrating strategy generally exploits tumor-targeted ligands to modify drugs so that the conjugate preferentially enters tumors and subsequently undergoes transcellular transport to penetrate tumors. However, this process shields ligands from their corresponding targets on the cell surface, possibly inducing an off-target effect during drug penetration at the tumor-normal interface. Herein, we first describe a selective tumor-penetrating drug (R11-phalloidin conjugates) for intravesical therapy of bladder cancer. The intravesical conjugates rapidly translocated across the mucus layer, specifically bound to tumors, and infiltrated throughout the tumor via direct intercellular transfer. Notably, direct transfer from normal cells to tumor cells was unidirectional because the pathways required for direct transfer, termed F-actin-rich tunneling nanotubes, were more unidirectionally extended from normal cells to tumor cells. Moreover, the intravesical conjugates displayed strong anticancer activity and well-tolerated biosafety in murine orthotopic bladder tumor models. Our study demonstrated the potential of a selective tumor-penetrating conjugate for effective intravesical anticancer therapy.

The advent of immunotherapy has marked a new era in cancer treatment, offering significant clinical benefits. Cell membrane as drug delivery materials has played a crucial role in enhancing cancer therapy because of their inherent biocompatibility and negligible immunogenicity. Different cell membranes are prepared into cell membrane nanovesicles (CMNs), but CMNs have limitations such as inefficient targeting ability, low efficacy, and unpredictable side effects. Genetic engineering has deepened the critical role of CMNs in cancer immunotherapy, enabling genetically engineered‐CMN (GCMN)‐based therapeutics. To date, CMNs that are surface modified by various functional proteins have been developed through genetic engineering. Herein, a brief overview of surface engineering strategies for CMNs and the features of various membrane sources is discussed, followed by a description of GCMN preparation methods. The application of GCMNs in cancer immunotherapy directed at different immune targets is addressed as are the challenges and prospects of GCMNs in clinical translation.

Bladder cancer (BC) accounts for roughly 3% of all cancer diagnoses in developed countries. The prognosis could be improved significantly if the cancer is detected and classified as either muscle‐invasive bladder cancer (MIBC) or non‐muscle‐invasive bladder cancer (NMIBC) as promptly as possible. A potential ray of hope for the treatment of BC has emerged with the rapid development of nanomedicine and microRNAs (miRNAs), which promise to have fewer adverse effects, more tumor‐inhibitory effects, and decreased drug resistance. The complex interplay between hereditary and environmental variables is the root cause of this malignancy. Gene expression can be regulated by miRNAs, which are small, non‐coding RNAs that can either prevent the translation of protein‐coding genes or cleave RNA transcripts at certain locations. Elevated genomics has enabled a more extensive investigation of miRNAs whose expression is considerably different in BC patients compared to healthy volunteers or between BC tumor tissues and peripheral tissues. miRNAs have recently been discovered to be important regulators of BC cell carcinogenicity. Inaccurate diagnoses and prolonged treatment delays are more likely to occur due to the current diagnostic process such as lack of sensitivity and specificity and poor image quality. Patients now have access to a plethora of treatment options, including but not limited to surgery, chemotherapy, immunotherapy, gene therapy, and other innovative medicines, and in some cases, combination therapies. BC is one of the deadliest and most disabling malignancies affecting the urinary tract. Cancer of the urinary bladder has a terrible propensity for being fatal. BC is an intricate illness whose development can be affected by multiple parameters. Standard treatments for BC increase prognosis and survival, although recurrence is a major concern for patients. miRNAs are naturally occurring, small RNA molecules that have been linked to cancer through their expression being dysregulated. miRNAs modulate many cellular activities including proliferation, migration, differentiation, and apoptosis. MiRNA dysregulation is recognized in BC, and miRNAs are used as diagnostic and prognostic indicators. However, this manuscript discusses the recent progress made in nanomedicine and the function of miRNAs in the pathogenesis and targeted therapy of BC.
