SUMMARY:Universal biology in adaptation and evolution: dimensional reduction\, and fluctuation-response relationship
DESCRIPTION:This talk will be presented online. Zoom link: 997 8258 4700 (pw: 1234) \nAbstract: A macroscopic theory for cellular states with steady-growth is presented\, based on consistency between cellular growth and molecular replication\, together with robustness of phenotypes against perturbations. Adaptive changes in high-dimensional phenotypes are shown to be restricted within a low-dimensional slow manifold\, from which a macroscopic law for cellular states is derived\, as is confirmed by adaptation experiments of bacteria under stress. The theory is extended to phenotypic evolution\, leading to proportionality between phenotypic responses against genetic evolution and by environmental adaptation\, which explains the evolutionary fluctuation-response relationship previously uncovered.   \nReferences \n\n Kaneko K.\, Life: An Introduction to Complex Systems Biology\, Springer (2006)\n K.

SUMMARY:A systems biology approach using multi-scale modeling to understand the immune response to tuberculosis infection and treatment
DESCRIPTION:This talk will be presented online. Zoom link: 997 8258 4700 (pw: 1234) \nAbstract: Tuberculosis (TB) is one of the world’s deadliest infectious diseases. Caused by the pathogen Mycobacterium tuberculosis (Mtb)\, the standard regimen for treating TB consists of treatment with multiple antibiotics for at least six months. There are a number of complicating factors that contribute to the need for this long treatment duration and increase the risk of treatment failure. The structure of granulomas\, lesions forming in lungs in response to Mtb infection\, create heterogeneous antibiotic distributions that limit antibiotic exposure to Mtb.   We can use a systems biology approach pairing experimental data from non-human primates with computational modeling to represent and predict how factors impact antibiotic regimen efficacy and granuloma bacterial sterilization. We utilize an agent-based\, computational model that simulates granuloma formation\, function and treatment\, called GranSim.  A goal in improving antibiotic treatment for TB is to find regimens that can shorten the time it takes to sterilize granulomas while minimizing the amount of antibiotic required. We also created a whole host model\, called HOSTSIM\, to study Mtb dynamics within a human host.  Overall\, we use these models to help better understand TB treatment and strengthen our ability to predict regimens that can improve clinical treatment of TB.

SUMMARY:Scaling behaviors in physiological fluctuations: relevance to circadian regulation and insights into the development of Alzheimer’s disease
DESCRIPTION:This talk will be presented online. Zoom link: 997 8258 4700 (pw: 1234) \nAbstract: Outputs from health biological systems display complex fluctuations that are not random but display robust and often self-similar (fractal) temporal correlations at different time scales— scaling behaviors. The scaling behaviors in the fluctuations of biological outputs such as neural activities\, cardiac dynamics\, motor activity are believed to be originated from feedbacks within the complex biological networks\, reflecting the system adaptability to internal and external inputs. Supporting this concept\, our studies have demonstrated a mechanistic link between the scaling regulation of physiological fluctuations and the circadian control system— a result of evolutionary adaptation to daily environmental light-dark cycles on the earth. In this talk\, I will discuss certain evidence for this ‘scaling-circadian’ link and its related implications. Moreover\, I will review some recent studies\, in which we examined how the scaling patterns of human motor activity fluctuations change with aging and in Alzheimer’s disease. Our results showed that (1) alterations in scaling activity patterns occur before the clinical manifestation of Alzheimer’s disease (i.e.\, cognitive impairment) and predict cognitive decline and the risk for Alzheimer’s dementia; and (2) the progression of Alzheimer’s disease accelerates the aging effect on the scaling activity patterns. Our work provides strong evidence that altered scaling activity patterns may also be a risk factor for neurodegeneration\, playing a role in the development and progression of Alzheimer’s disease.
