Ot1 mice
The ot ii peptide is a significant entity in immunological research, primarily recognized for its role in T-cell activation and response. Specifically, it refers to a peptide derived from ovalbumin (OVA), a well-studied protein found in egg whites. This OVA peptide sequence, most commonly characterized as residues 323-339 or a similar C-terminal epitope spanning amino acids 329-337, serves as a critical antigen for specific T-cell populations. The OT-II designation, often seen in conjunction with OTII mice, refers to a transgenic mouse model engineered to express a T cell receptor (TCR) that is highly specific for this particular OVA peptide presented in the context of the MHC class II molecule I-Ab作者:A Leyton-Pereira·2025—These findings support CD6 as a “dual” immunomodulatory receptor capable of either amplify or attenuate T-cell activation in different experimental contexts..
The significance of the ot ii peptide lies in its utility as a tool for investigating CD4+ T cell function.Rag2/OT-II (11490) Researchers frequently employ this peptide to activate OT-II T cells in laboratory settings. This activation process is fundamental for studying various aspects of adaptive immunity, including T cell development, antigen-specific CD4 T cell responses, T-T interactions, and the development of hypersensitivity responses. The ability to reliably stimulate OT-II CD4+ T cells with the OVA peptide allows for controlled experiments to elucidate complex immunological mechanisms.

Beyond basic research, the ot ii peptide and its associated models contribute to broader immunological questions. For example, research on vaccine delivery systems and the mechanisms of antigen presentation often involves the ot ii peptide.作者:JM Robertson·2000·被引用次数:478—DO11.10 and OT-II T cells areboth specific for a C-terminal epitopewhose core encompasses amino acids 329-337. Studies have explored how different delivery methods, such as gas plasma technology, can augment the presentation of ovalbumin to OT-II T cells. The peptide itself can bind directly to MHC-I/II on the cell surface, often without the need for extensive antigen processing, to activate OT-I CD8 and OT-II CD4 T cells.Rag2/OT-II (11490) This direct binding capability underscores the importance of the ot ii peptide in understanding T-cell activation pathways.
Moreover, the ot ii peptide plays a role in understanding immune regulationThe Rag2 knockout /OT-IImouse model is deficient in recombination activation gene 2 and carries a transgene to facilitate T cell biology research.. For example, studies have investigated T regulatory cells and their ability to mediate suppression, with OT-II cells being used as a control or experimental population when SMARTA T cells are not activated.A protective vaccine delivery system for in vivo T cell ...

The ability to activate CD4+ T cells from OTII mice with OVA peptide is a cornerstone of many experimental designs.
In summary, the ot ii peptide, a specific sequence from ovalbumin, is a fundamental research tool in immunology. Its precise recognition by OT-II T cells in the context of MHC class II molecules allows for the detailed study of CD4 T cell function, activation, and regulation. Whether investigating fundamental immunological processes, developing novel vaccines, or exploring immune modulatory strategies, the ot ii peptide remains a critical and verifiable component in the advancement of immunological knowledge.Ovalbumin(323−339) Peptide Binds to the Major ... The term peptide itself is central to its function, as it's the molecular structure that initiates the immune response. The related search term Ovapeptide further solidifies its connection to ovalbumin. The II in ot ii peptide specifically denotes its association with the CD4 co-receptor and MHC class II presentation, distinguishing it from similar peptides recognized by other T-cell populations.
