Investigating The Immunostimulatory Potential Of Dsrna-Silk Nanoparticle Complexes In Melanoma, Samuel J. Peters
Investigating The Immunostimulatory Potential Of Dsrna-Silk Nanoparticle Complexes In Melanoma, Samuel J. Peters
Theses and Dissertations (Comprehensive)
The rate of resistance to immune checkpoint inhibitor treatment in metastatic melanoma is quite high, with an overall rate of 70%. Melanoma achieves these high rates of resistance by suppressing the immune response in the tumour microenvironment (TME), making them immunologically “cold”. The type 1 interferon response could be leveraged to initiate immune responses in melanoma, making their “cold” TMEs “warm” again. Double-stranded ribonucleic acids (dsRNAs) are potent activators of an innate immune response; however, they are susceptible to degradation by nucleases present in the body and need a carrier. Silk nanoparticles (SNPs) are an ideal drug-delivery platform as they …

Cancer is a group of diseases characterized by abnormal and uncontrolled cell division, which typically results in the formation of tumours. Even with advances in treatments, cancer remains one of the leading causes of death globally. Melanoma is an aggressive form of skin cancer which is highly malignant, develops in the pigment-producing cells of the skin, melanocytes, and in the late stages of the disease poses a significant challenge for therapeutic intervention due to its multidrug resistance. The innate immune system is the first line of defence against invading pathogens, including viruses, bacteria, and fungi, and can recognize and destroy …

An estimated 1 in 70 women will be diagnosed with ovarian cancer in their lifetime. Despite advanced detection and treatment methods, it remains a silent killer with an expected survival rate of 50%. A developing method in cancer treatment is the use of compounds that stimulate the immune system to aid in the body's fight against the disease. This project focused on the use of the potent immune stimulant double-stranded RNA (dsRNA), commercially available as polyinosinic:polycytidylic acid, poly(I:C), to induce cytotoxicity in two ovarian cancer cell lines; SKOV-3 and OVCAR-3. Some challenges exist with the delivery of dsRNA due to …
