Weissman directs a research group consisting of graduate students, medical student-scientists, and postdoctoral fellows, all of whom study stem cell biology and regenerative medicine. He has trained and supervised hundreds of students and fellows, authored more than scientific articles and has numerous awards and honorary degrees for his research accomplishments. Weissman is an expert in the field of hematopoiesis, leukemia, and hematopoietic stem cells [HSC], and most recently, the clonal events leading from HSC to leukemia stem cells.. His research also encompasses the phylogeny and developmental biology of the cells that make up the blood-forming and immune systems. He has a laboratory at Hopkins Marine Station of Stanford University, where he studies the histocompatibility systems in colonial protochordate, a system which he proposed evolved to prevent predatory germline stem cell lineages from passing from one individual to another in multi-individual colonies that share a common extracorporeal blood vascular system; only histocompatible stem cells can colonize allogeneic natural parabionts.

Irving Weissman's Profile | Stanford Profiles

The blood-brain barrier BBB is the interface between the peripheral circulation and the central nervous system. This multi-dimensional structure is composed of specialized cerebral and spinal microvessels and surrounding cells and matrix. It serves important regulatory functions by differential permeability. It is also subject to modification by many pathophysiological factors. This talk will present ongoing BBB studies in our own laboratory and others, focusing on the following topics: III neurotoxins penetrating the BBB to induce neuropathology; III neurotoxins that increase the general permeability of the BBB or affect transport systems for other essential substances; 3 neurotrophins as pro-drugs to penetrate the BBB in either the native state or after modification by biotechnology; 4 circulating peptides that serve as either neurotoxins or trophic factors besides regulating behavior; and 5 how cytokine transport across the BBB affects neuroplasticity.

All biological systems depend on signals for coordination: signals which pass information among agents that run the gamut from cells to organisms. However, their very importance makes signals vulnerable to subversion. How can a receiver know whether a signal is honest or deceptive?
