With the aim to develop a prognostic IDO1-based immune gene signature, biological and clinical data of 732 patients with newly diagnosed, non-promyelocytic AML were retrieved from public datasets and analyzed using established computational pipelines. (ntu.ac.uk)
STAT6 (signal transducer and activator of transcription 6) is a member of the STAT family of cytoplasmic transcription factors, which regulate gene expression by transmitting signals to the nucleus and binding to specific DNA promoter sequences. (biocare.net)

Together, METTL3 is a therapeutic target in NAFLD-HCC, especially in conjunction with immune checkpoint blockade (ICB) therapy. (bvsalud.org)

Eat a gut-friendly diet, including lots of plants, that support optimal immune function. (naturalnews.com)
While most people understand the importance of a balanced diet, regular exercise, and sufficient sleep for immune function, there is another crucial factor that often goes overlooked: gut health. (peptiko.gr)
This network, known as gut-associated lymphoid tissue (GALT), plays a pivotal role in immune function. (peptiko.gr)

Safe, reliable strategies for the induction of full tolerance have not yet been developed. (medscape.com)

Given the emerging role of immunotherapies for AML, our findings support the incorporation of immune biomarkers into current AML classification and prognostication algorithms. (ntu.ac.uk)
