APC-targeted DNA vaccines: the role of CCL19 in immune cell recruitment and early onset of the immune response

Key Points

• This study aims to explore the role of CCL19 in enhancing the effectiveness of DNA vaccines by improving immune cell recruitment.
• Utilized a fusion approach to attach CCL19 to neoantigens.
• Assessed chemotactic properties of CCL19 in immune response modulation.
• Evaluated the immunogenicity and tumor control in response to the DNA vaccine.
• Demonstrated that CCL19 significantly improves immune cell recruitment.
• Enhanced DNA vaccine performance leads to better tumor control.
• Showed that CCL19 retains chemotactic and signaling properties essential for effective immune response.
