安全有效的免疫佐剂通常对疫苗至关重要。然而,许可疫苗佐剂的选择是有限的,特别是对于皮内注射的疫苗。我们发现,在不使用其他化学或生物制剂的情况下,短时间照射小面积皮肤的非组织损伤性近红外 (NIR) 激光可显着增强皮内流感疫苗接种的免疫反应,且不会增强 IgE。与未佐剂的疫苗相比,近红外激光佐剂疫苗在鼠流感致死攻击模型中提供了更强的保护。我们表明,近红外激光治疗可诱导皮肤中特定趋化因子的表达,从而导致树突状细胞的募集和激活,并且可以安全地用于小鼠和人类。近红外激光佐剂技术提供了一种新颖、安全、低成本、易于使用、潜在广泛适用且临床可行的方法来增强疫苗功效,作为化学和生物佐剂的替代品。
Safe and effective immunologic adjuvants are often essential for vaccines. However, the choice of adjuvant for licensed vaccines is limited, especially for those that are administered intradermally. We show that non-tissue damaging, near-infrared (NIR) laser light given in short exposures to small areas of skin, without the use of additional chemical or biological agents, significantly increases immune responses to intradermal influenza vaccination without augmenting IgE. The NIR laser-adjuvanted vaccine confers increased protection in a murine influenza lethal challenge model as compared to unadjuvanted vaccine. We show that NIR laser treatment induces the expression of specific chemokines in the skin resulting in recruitment and activation of dendritic cells and is safe to use in both mice and humans. The NIR laser adjuvant technology provides a novel, safe, low-cost, simple-to-use, potentially broadly applicable and clinically feasible approach to enhancing vaccine efficacy as an alternative to chemical and biological adjuvants.
