Cell-cell fusion is critical for the development and transport capacity of the placenta during pregnancy. Impairments in this process occur in pregnancy complications such as preeclampsia (PE). We have identified a novel pathway (LY6E) regulating placental cell-cell fusion which is also dysregulated in human pregnancies complicated by PE. In the current proposal we will investigate the mechanisms by which LY6E mediates cell-cell fusion and examine its role in the development of PE.

Summary
When cells of the human body become cancerous or infected with virus, the body's immune system engages cytotoxic lymphocytes, known as "killer cells", that secrete an auxiliary of toxic proteins to eliminate these cells. The aim of this study is to investigate the mechanisms by which these critical immune cells accomplish this task. Importantly, humans who are genetically lacking in critical constituents of the cytotoxic lymphocyte are less able to fight off a viral infection and may be at a hig ....When cells of the human body become cancerous or infected with virus, the body's immune system engages cytotoxic lymphocytes, known as "killer cells", that secrete an auxiliary of toxic proteins to eliminate these cells.

Summary
Malaria parasites cause profound human disease through infection of the red blood cell. How parasites break into the red cell is incompletely understood. Foremost, the parasite must induce radical changes in its structural integrity to enter, but to date no study has been able to precisely map these cellular events. In this research program we aim to dissect the entire process using state-of-the-art imaging, molecular biology and proteomics to shine new light on this key step in malaria disease ....Malaria parasites cause profound human disease through infection of the red blood cell.
