Core Insights - The 2025 Nobel Prize in Physiology or Medicine was awarded to three scientists for groundbreaking discoveries in regulatory T cells, revealing how the immune system maintains self-balance through "peripheral immune tolerance," which is crucial for understanding autoimmune diseases and developing new cancer immunotherapy strategies [4][5] - Traditional animal models struggle to accurately simulate the human immune system due to species differences, leading to challenges in mechanism research, clinical translation, and model construction [4] - Humanized immune system mice provide a key technology to address these issues, allowing for effective preclinical evaluation of candidate drugs, significantly reducing subsequent development risks, and providing a reliable platform for assessing new cell therapies and bispecific antibodies [5] Course Overview - An online course titled "Applications of Humanized Immune System Mice in Tumor Immunity and Autoimmune Diseases" will be held on October 21, featuring Dr. Yu Jing, a senior scientist at Saiye Bio, focusing on scientific decision-making for obtaining valuable experimental data [5][7] - The course will cover the following topics: 1. Advances in tumor immunity: Translating Nobel-level discoveries into new treatment strategies and related research dynamics [7] 2. Model development history: Reviewing the evolution of models and the characteristics and applicable scenarios of PBMC, HSC, and other construction strategies [7] 3. Optimization strategies and application cases: Emphasizing research on tumor immunity and autoimmune diseases, drug efficacy, and safety evaluation [7] 4. Interactive session: The lecturer will answer common questions related to disease research [7] Research Applications - The huHSC-C-NKG-ProF model has been utilized in significant research, including: 1. CAR-T cell therapy for solid tumors, revealing how Foxp3 regulates CAR-T cell metabolism to enhance treatment efficacy [12] 2. Liver cancer immune evasion studies, identifying ETV5 as a potential biomarker for prognosis and a target for new treatment strategies [12] - Saiye Bio's humanized immune system mice, particularly the huHSC-C-NKG-ProF model, can reconstruct various human immune cells, providing a robust platform for research [13][14] Product Offerings - Saiye Bio offers several humanized immune system models, including: - huHSC-C-NKG-ProF: Full immune system reconstruction with a humanization rate of 40-60% after 8 weeks [16] - huHSC-C-NKG-ProM: Reconstructs lymphoid T and B cells with a similar humanization rate [16] - huHSC-C-NKG-ProN: Focuses on T, B, and NK cells with minimal myeloid development [16] - huHSC-C-NKG: Supports long-term presence of human cells with a lifespan exceeding one year [16] - huPBMC-C-NKG: Primarily reconstructs lymphoid T cells with a fast reconstruction speed [16]
