"Key drivers, and epidemiological dynamics of drug-resistant tuberculosis: A model-based approach"


For the first time in many decades, new first-line drug regimens are being considered for treatment of tuberculosis (TB), which is the leading infectious disease source of mortality in the world, with an estimated 1.8 million TB-related deaths in 2015. A key concern with the launch of new drug regimens is the potential for rapid emergence of resistance.  Since population-level data on resistance cannot be collected in advance, epidemiological models become important tools for understanding the drivers and dynamics of resistance before novel drug regimens are launched. I will discuss model-based approach to uncover epidemiology of drug-resistant TB (DR-TB) by identifying roles of key drivers, and by describing short- and long-term dynamics of DR-TB.

“Visualizing the dynamic interactions between Plasmodium and mosquitos.”

Malaria is a mosquito-borne disease responsible for over 200 million cases and 400,000 deaths each year. Efforts to reduce malaria transmission include blocking Plasmodium parasite development inside the mosquito vector. After a mosquito ingests infected blood, the parasite will invade the midgut which causes nitration reactions and irreversible damage in the mosquito. Invasion also stimulates hemocytes, cells part of the mosquito’s immune system. Parasites persist if they are able to migrate out the damaged cell and remain undetectable from hemocytes. We have developed live imaging methods to capture these processes. Our results show that immune responses are important to lower parasite survival within the mosquito.

Biology Class of '88 Lectures:

Dr. Douglas Melton, Harvard Stem Cell Institute

12:30pm, MBH 216 (Science Talk):  
Applied developmental biology: Making pancreatic

 "One goal of regenerative medicine is to replace missing or defective cells.  Diabetics suffer from the absence of insulin-producing pancreatic beta cells and a possible solution, in principle, is to use human stem cells to make new functional beta cells.  Advances in directing the differentiation of pluripotent stem cells has advanced to the point where functional beta cells can be produced in vitro and done so at a scale that enables transplantation studies and clinical trials.  The state of this field of human developmental biology and the challenges ahead will be discussed." 

4:30pm, MBH 216:  General Audience Talk: 
"The promise of stem cells for cures and improved human health

"Human stem cells are a relatively new discovery in biomedicine.  How were these cells discovered and what is their potential?  This talk will consider the biology of stem cells and point to potential applications for new treatments of diabetes, brain and other diseases as well as enabling longer and healthier lives."
