Unlike conventional chemotherapies that can have widespread systemic toxicity, oncolytic peptides are designed for greater selectivity, often targeting the unique or altered membrane compositions of malignant cells.Abstract 328: Antitumor activity of the oncolytic peptide LTX ... For instance, research has explored branched oncolytic peptides designed to target specific cell surface molecules, enhancing their precision. Examples like BOP7 and BOP9 highlight the development of such targeted approaches.

Beyond direct cytotoxicity, oncolytic peptides play a crucial role in remodeling the tumor microenvironment and potentiating anticancer immunity. They are highly effective in this regard through multiple mechanisms. Upon inducing cancer cell death, these peptides can trigger the release of damage-associated molecular patterns (DAMPs), which are key mediators of immunogenic cell death (ICD). This release essentially signals to the immune system that cancer cells are present and need to be eliminated, thereby stimulating a robust anticancer immune response.作者：H Liu·2024·被引用次数：50—Oncolytic peptides that can induce membrane lysis-mediated cancer cell deathand subsequent anticancer immune responses, has provided a new paradigm for cancer ... This phenomenon, where oncolytic peptides drive immunogenic cell death, is a critical aspect of their therapeutic potential, turning the tumor into a site that actively recruits and activates immune cells.

This includes the design of novel molecularly targeted oncolytic peptides, such as those demonstrating promising efficacy for treating therapy-resistant progressive neuroblastoma, as validated through RNA sequencing. Furthermore, the conjugation of oncolytic peptides with other therapeutic modalities is being investigated. For example, EP-100, a novel LHRH receptor targeted cytolytic peptide conjugate, is designed to specifically kill LHRH receptor-positive cancer cells. The advancement from simple peptides to more complex structures like polymer chimera of stapled oncolytic peptides also signifies the ongoing innovation in this area.
