SUMMARY:Séminaire du LPTMS : Andreas Mayer (Princeton) - LPTMS (100% onlin
 e seminar) - 12 Jan 21 14:00
DESCRIPTION:A Langevin approach to the dynamics of the human immune system\
 nAndreas Mayer (Princeton)\n\nOnline seminar --- Zoom Meeting ID: 951 1138
  2280 -- Passcode: Ask L. Mazza or D. Petrov --\n\n\nNote the unusual time
 !\n\n\nNew sequencing techniques put studying populations with a very larg
 e number of distinct species within reach. As the number of species increa
 ses\, so does the number of interactions between species and with the envi
 ronment. Statistical physics provides a framework to adapt ecological theo
 ry to this new setting: key phenomena can be captured by replacing interac
 tions with effective stochastic forces. In my talk\, I will present how we
  have applied this Langevin approach to study the dynamics of adaptive imm
 unity. We propose a theory for the emergence and maintenance of an observe
 d power-law scaling in the sizes of different immune cell populations. Rem
 arkably\, linking our theory to snapshots of immune composition at differe
 nt ages we demonstrate that exposures in infancy leave a lifelong imprint 
 with implications for pathogen defense and autoimmunity.\n\n
