Abstract
Neuronal signals have emerged as pivotal regulators of B cells that regulate antitumor immunity and tumor progression. However, the functional relevance and mechanistic basis of the effects of the neurotransmitter dopamine (DA) on tumor immunity remain elusive. Here, we discovered that plasma DA levels are positively correlated with circulating B cell numbers and potently activate B cell responses in a manner dependent on the DRD5 receptor. Notably, DRD5 signaling enhanced the Janus kinase 1 (JAK1)-STAT1 signaling in B cell responses, which enhanced B cell activation and increased antigen presentation and co-stimulation, resulting in increased expansion and cytotoxicity in tumor-specific effector of T cells. Our findings demonstrate that DA signaling suppresses tumor progression and highlight DRD5 as a promising target for cancer immunotherapy.
期刊介绍：
Cell Reports publishes high-quality research across the life sciences and focuses on new biological insight as its primary criterion for publication. The journal offers three primary article types: Reports, which are shorter single-point articles, research articles, which are longer and provide deeper mechanistic insights, and resources, which highlight significant technical advances or major informational datasets that contribute to biological advances. Reviews covering recent literature in emerging and active fields are also accepted.
The Cell Reports Portfolio includes gold open-access journals that cover life, medical, and physical sciences, and its mission is to make cutting-edge research and methodologies available to a wide readership.
The journal's professional in-house editors work closely with authors, reviewers, and the scientific advisory board, which consists of current and future leaders in their respective fields. The advisory board guides the scope, content, and quality of the journal, but editorial decisions are independently made by the in-house scientific editors of Cell Reports.
