Malaria presented by Joseph DeRisi Part 3: Drug Development (24:13)

submitted by: video_collector

This brief set of three lectures gives a very general overview of malaria, the disease and Plasmodium falciparum, the causative agent of the most deadly form. Basic research as well as drug development efforts will also be covered in parts two and three of this series.

Intracellular Parasitism by Trypanosoma cruzi and Leishmania": Part 3: Current Research: Strategies for Cell Invasion and Intracellular Survival (33:43)"

submitted by: video_collector

In the third part of this lecture, I will discuss current work from our laboratory on mechanisms used by the intracellular parasites Trypanosoma cruzi and Leishmania to interact with mammalian cells. In addition to clarifying specific molecular strategies used by these parasites to infect and survive within host cells, these studies also led, in some instances, to unexpected insights on novel pathways regulating mammalian cell function.

Intracellular Parasitism by Trypanosoma cruzi and Leishmania: Part 2: Leishmania spp and Leishmaniasis (13:36)

submitted by: video_collector

In the second part of this lecture, I will present background material on Leishmania, the intracellular protozoan parasites responsible for severe human pathology in several parts of the world. I will discuss the main disease forms, the history of identification of the causative agent and form of transmission, and recent discoveries that established important concepts in our understanding of this increasingly serious infectious disease.

Danger from the Wild: HIV, Can We Conquer It? Part 3: The Grand Challenge: Engineering Immunity (18:51)

submitted by: video_collector
In this last segment, I describe another gene therapy strategy for HIV in which we propose to develop antibody-like proteins that can be expressed by a patient's B cells and will target the HIV virus for destruction. To achieve this objective, hematopoietic (blood) stem cells must to be targeted with the gene, which will ultimately develop into B cells that express the therapeutic molecule. The ultimate goal is to produce a life-long supply of anti-HIV neutralizing antibodies. In this...

Danger from the Wild: HIV, Can We Conquer It?": Part 2: Why Gene Therapy Might be a Reasonable Tool for Attacking HIV (30:08)"

submitted by: video_collector
In part 2, I describe the growing health problem that is facing the world with the spread of HIV and the limitations of current drug therapies and vaccine strategies. We need new ideas for tackling this problem. Here and in the next segment, I describe bold strategies of using gene therapy to conquer HIV, The approach that I describe in this segment involves gene therapy to produce short hairpin RNAs (siRNA) that target the destruction of a critical co-receptor of HIV, which the viruses that...

Plant Viruses and Crops ": Part 2: Genetic Engineering for Virus Resistance in Plants: Different Viruses Demand Different Strategies (01:02:11) "

submitted by: video_collector

The second part of the lecture will relate how this information can be used to produce crops resistant to specific viruses through different biotechnology strategies.

Apicomplexan Parasites, Pathogen Genome Informatics, and the Evolution of Eukaryotic Organelles: Part 3C: Designing and mining pathogen genome databases: From genes to drugs and vaccines (25:45)

submitted by: video_collector
With the emergence of genomic-scale datasets representing all of the genes in the genome, all of the proteins in a cell or tissue, and all of the interactions and signals in an organism, biologists are increasingly faced with the challenge of how to store, integrate, and interrogate this information. How can we effectively mine large-scale datasets to expedite biological discovery, for example in the identification of new targets for anti-parasitic drug and vaccine design? Computational...
