Research

Specific Clinical/Research Interest: Chemokines; leukocyte trafficking; angiogenesis; lymphoid development; mouse genetics

Current Students: Luciana Muniz

Postdoctoral Fellows: Gerold Bongers, Erik Slinger

Research Personnel: Research Assistant: Michelle Pacer

Summary of Research Studies:
We use genetic approaches in mice to study the function of chemokines and their receptors in leukocyte trafficking, angiogenesis, inflammation and cancer. Recent work in the laboratory focuses:

1) on the role of chemokine-like molecules encoded by herpes and poxviruses in immune evasion and tumorigenesis; and

2) on the role of chemokines in lymphoid organogenesis and autoimmunity.

Industry Relationships

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.

Below are financial relationships with industry reported by Dr. Lira during 2013 and/or 2014. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.
