Scientist Solutions: International Life Science Community By Scientists For Scientists

Thanks to our sponsors who make this site possible
samm' Bench [how it works]
Space
My Bench Space is your space on Scientist Solutions, with both a private area where you can keep track of your account settings and favorite postings, and a public area where you can upload your picture, customize your profile, or start a blog

My Summary
Keeps a log of the topics you've started, the replies you've made, protocols or events you've posted, etc. Your summary will show up in your public profile.

My Blogs
You can create as many blogs as you like. They'll be viewable by anyone who looks at your profile, and they will also be indexed and listed in The Forums section of Scientist Solutions

My Lab Drawer (private)
As you browse through Scientist Solutions, you may see a topic, event, job or protocol that you'd like to store so that you can find it again easily. By clicking the "Save to My Bench Space" button next to any item on our site, you will put that item in your lab drawer for future reference.
You can also add fellow scientists to your lab drawer by clicking the "Save this scientist to My Bench Space" link next to that member's name in their posts or Bench Space profiles.

My PubMed Alerts (private)
This really cool tool allows you to set up email notifications whenever and article in your area of interest (specified by keyword is published in PubMed

About My Research

We currently work on interactions of surfactant proteins with the immune system. In addition to some work with macrophages, DCs and neutrophils, my research remains primarily focussed on sub-populations of T cells in the lung, spleen and lymph nodes in both in vivo and ex-vivo models of asthma, atopic allergy and inflammation. I consider this to be a natural "real world" application of my graduate school thesis, which dealt with T cell activation and costimulation.

Previous post-doctoral work with polycystin-1 (PC1), the protein affected in most cases of ADPKD, implicated it in a novel pathway that can control the transduction of mechanical signals at the cell surface to gene expression. PC1 binds to the gene expression regulators STAT6 and P100. A halt in renal fluid flow results in cleavage of PC1 and movement of STAT6 to the nucleus. Cyst-lining epithelial cells in ADPKD patients exhibit highly elevated levels of nuclear STAT6 and the cleaved PC1 tail, which suggests that this novel pathway is inappropriately activated. STAT6, P100 and other proteins that regulate this pathway may therefore be promising new targets for therapeutic intervention. The role of STAT6 with respect to cell growth, signaling and death are being studied in context of the PC1 tail in renal epithelial cells. To test the hypothesis that STAT6 function is a requirement for cyst formation, STAT6 deficient mice are being crossed with PKD models and parameters of cyst formation and renal function investigated.
