Interests<\/u><\/p><p>Glycosylation is an important post-translational modification that regulates a wide range of cellular processes. Cell-surface glycans interact with glycan-binding receptors and other ligands to modulate intracellular signaling, cell proliferation, differentiation, oncogenic transformation, immune recognition, and immune surveillance. Tumor and leukemia cells frequently exhibit tumor-associated carbohydrate antigens (TACAs) and aberrant hypersialylation. Through interactions with sialic acid-binding immunoglobulin-like lectins (Siglecs) expressed on immune cells, these altered glycan structures may attenuate immune recognition and effector functions, thereby contributing to immune evasion.<\/p><p>Our research focuses on Siglec-7 and investigates the interplay among cell-surface glycan structures, immune-receptor signaling, mitochondrial function, and cellular metabolism. Major research areas include:<\/p><ol><li>Cell-surface glycosylation and natural killer cell immune surveillance<br \/>We investigate how glycan structures, sialylation, and Siglec-7 ligands on tumor and leukemia cells regulate natural killer (NK) cell recognition, degranulation, cytotoxicity, and cytokine production.<\/li><li>Siglec-7 regulation of mitochondrial function and metabolism in NK cells<br \/>We study how Siglec-7 connects mitochondrial fission and fusion, oxidative phosphorylation, energy metabolism, and metabolic reprogramming to restrain the cytotoxic function of human NK cells.<\/li><li>Siglec-7 in megakaryopoiesis and thrombopoiesis<br \/>We investigate the expression and function of Siglec-7 during megakaryopoiesis and thrombopoiesis, with particular emphasis on its relationship with mitochondrial dynamics and its physiological roles in megakaryocytic differentiation, platelet production, and platelet function.<\/li><li>Hematopoietic differentiation and hematological malignancies<br \/>Using models of erythropoiesis, megakaryocytic differentiation, leukemia, and NK-cell biology, we examine the molecular mechanisms linking glycan remodeling, transcriptional and epigenetic regulation, mitochondrial metabolism, and immune effector functions.<\/li><li>Glycan-related biomarkers and translational applications<br \/>We aim to identify glycan- and Siglec-7-related molecular biomarkers for evaluating immune-cell function, tumor immune evasion, hematological disorders, and platelet biology, and to explore their potential applications in disease stratification, prognostic assessment, and immunotherapeutic development.<\/li><\/ol><p>Overall, our research centers on the integrated glycan\u2013Siglec-7\u2013mitochondria\u2013immune and hematopoietic function axis. We seek to clarify how cell-surface glycan signals are translated into mitochondrial and metabolic responses that regulate immune-cell effector functions and hematopoietic-cell differentiation.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-3858e4f elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"3858e4f\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-db100aa\" data-id=\"db100aa\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-04a80fc elementor-widget elementor-widget-heading\" data-id=\"04a80fc\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">\u7814\u7a76\u8457\u4f5c<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9af8e28 elementor-widget elementor-widget-text-editor\" data-id=\"9af8e28\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<ol><li>Su SC, Tsao NT, Wang TL, Shih YC, <strong><u>Twu YC<\/u><\/strong>.
