Provided is an antibody that specifically binds human αvββ and blocks binding of TGFp peptide to αvβ8, wherein the antibody binds to the specificity determining loop (SDL) of human β8. In some embodiments, the antibody further binds to one, two, or all three of the human av-head domain, the al helix of human β8, or the al helix of human β8. In some embodiments, the antibody is humanized or chimeric. In some embodiments, the antibody is linked to a detectable label. Also provided is a method of enhancing an immune response in a human individual, comprising administering a sufficient amount of the antibody to the individual, thereby enhancing an immune response. Also provided are pharmaceutical compositions comprising the anti-αvββ antibodies or antigen-binding molecules thereof.
本研究提供了一种抗体,它能特异性地结合人 αvββ 并阻断 TGFp 肽与αvβ8 的结合,其中该抗体与人β8 的特异性决定环(SDL)结合。在某些实施方案中,抗体进一步与人类 av 头结构域、人类 β8 的 al 螺旋或人类 β8 的 al 螺旋中的一个、两个或全部三个结合。在某些实施方案中,抗体是人源化的或嵌合的。在某些实施方案中,抗体与可检测标签相连。还提供了一种增强人体免疫应答的方法,包括向人体施用足量的抗体,从而增强免疫应答。还提供了包含抗αvββ抗体或其抗原结合分子的药物组合物。
