    Collapse Overview
    The primary goal of our research is to understand molecular mechanisms regulating tumor growth, inflammation and metastasis. Our laboratory is focused on the study of signaling cascades that regulate recruitment and activation of immunosuppressive macrophages in solid tumors with special focus on neuroblastoma and pancreatic adenocarcinoma.

    Altmetrics Details PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
