Minor lymphocyte stimulating antigens, also known as minor LSAs, refer to proteins that can stimulate the immune system by activating lymphocytes, leading to an immune response. Synonyms for minor lymphocyte stimulating antigens primarily include secondary lymphocytic activating peptides, alternative lymphocytosis inducers, and non-major lymphocyte activators. These terms emphasize their role in promoting lymphocyte activation and immune system stimulation. Other synonyms may include peripheral antigens inducing lymphocytic responses and non-dominant leukocyte-activating agents, highlighting their capacity to initiate a cellular response from secondary immune cells. Overall, these different synonyms help to convey the various aspects and functions of minor lymphocyte stimulating antigens in immune system regulation.
