BUTANTAN INSTITUTE | Brazil
Dr. Ivana Vieira De Mello Loureiro cultivated a distinguished path in immunology from her medical graduation to advanced research, with a doctorate focused on human colostrum IgA antibodies reactive with colonization and pathogenic factors of Escherichia coli enteropathogenic strains. she subsequently served at the renowned Instituto Butantan as a full-time scientific technical research assistant, contributing to flow cytometry, immunopathology and training of students in immunological methods. her work spans immunology, immune response regulation and microbiology, bringing together applied immunology and human health sectors via investigations of peyer’s patches, oral BCG immunization, lymphocyte responses and hormonal influence on B cells emerging from the gut-associated lymphoid tissue. although precise citation-metrics (h-index, total documents, citations) are not publicly available from the source consulted, she is a seasoned researcher whose legacy lies in immunological characterisation of human colostral IgA, functional assays and flow-cytometric applications in immunopathology. her influence is evident in the training of scientists, implementation of cytometry services, and bridging of basic immunological research with maternal-infant health contexts. her legacy continues as she remains active in specialised technician-scientific roles, supporting immunology research infrastructure and mentoring future generations, thereby ensuring her contributions will endure well into emerging immunological challenges.
