DESCRIPTION:Optimal immune systems\nAleksandra Walczak (LPT-ENS\, Paris)\nN
 OTE THE NEW LOCATION (due to renovation work at LPS)\n\nBiological organis
 ms have evolved a wide range of complex strategies to defend themselves ag
 ainst pathogens. I will present a common evolutionary framework that balan
 ces the benefits and costs involved in protection against pathogenic envir
 onments to maximize the long growth rate of populations. I will show that 
 such a general evolutionary perspective recovers the basic forms of known 
 immunity. I will then focus on adaptive immunity which is based on a combi
 natorically encoded repertoire of receptors that protects organisms from a
  diverse set of pathogens. A well-adapted repertoire should be tuned to th
 e pathogenic environment to reduce the cost of infections.  I will discuss
  a general approach for predicting the optimal repertoire that minimizes t
 he cost of infections contracted from a given distribution of pathogens.\n
