چکیده

Abstract Patients with locally advanced and metastatic urothelial carcinoma have a low survival rate (median 15.7 months, 13.1–17.8), 23% response to monotherapy treatment anti-PD-L1 immunotherapy. We recently reported the potent effects of i.v. infusions immune modifying poly(lactic-co-glycolic acid) (PLGA) nanoparticles (IMPs; named ONP-302) both decrease B16.F10, MC-38, LLC, 4T1 tumor growth allow for B16.F10 responsiveness anti-PD-1 treatment. next sought determine if ONP-302 could significantly more clinically relevant BBN-carcinogen induced bladder cancer. The present data show that decreases cancer stage overall weight. While minor epithelial hyperplasia remained, inhibited widespread in situ muscle invasive development, as compared saline treated mice. Mechanistically, infusion decreased via activation cGAS/STING pathway within myeloid cells, subsequently increased CD8+ T cell NK IL-15. In subsequent studies assess cellular mechanisms involved function, we found vitro rapidly oxidized DNA cells took up PLGA was supernatant well. Furthermore, co-treatment DNase STING mediated cytokine production. These findings indicate allows control reprogramming inducing activation, increases rates,

Immunotherapy for Breast Cancer Treatment

Breast cancer, as a heterogeneous disease, includes a wide range of pathological and clinical behaviors. Current treatment protocols, including radiotherapy, chemotherapy, and hormone replacement therapy, are mainly associated with poor response and high rate of recurrence. Therefore, more efforts are needed to develop alternative therapies for this type of cancer. Immunotherapy, as a novel str...

Immunotherapy for bladder cancer

It is nearly 40 years since Bacillus Calmette-Guérin (BCG) was first used as an immunotherapy to treat superficial bladder cancer. Despite its limitations, to date it has not been surpassed by any other treatment. As a better understanding of its mechanism of action and the clinical response to it have evolved, some of the questions around optimal dosing and treatment protocols have been answer...

Society for Immunotherapy of Cancer consensus statement on immunotherapy for the treatment of bladder carcinoma

The standard of care for most patients with non-muscle-invasive bladder cancer (NMIBC) is immunotherapy with intravesical Bacillus Calmette-Guérin (BCG), which activates the immune system to recognize and destroy malignant cells and has demonstrated durable clinical benefit. Urologic best-practice guidelines and consensus reports have been developed and strengthened based on data on the timing,...

Dendritic Cell Immunotherapy, the Next Step in Cancer Treatment

Cancer immunotherapy has gained a lot of interest over the past few years due to the success of immune checkpoint inhibitors in treating cancer (1, 2). Immune checkpoint inhibitors, such as monoclonal antibodies against cytotoxic T-lymphocyte–associated antigen 4 (CTLA-4) and programmed death 1 (PD-1), have been shown to increase survival of patients with advanced cancers (1, 2). These in...
