this increased responsiveness , together with the higher igm/igg ratios for all ig isotypes and an otherwise similar order of isotype distribution ( gamma 1 greater than gamma 2b greater than gamma 2a = epsilon greater than or equal to alpha ) as in controls , suggests that a hyperresponsive , but less mature igd- b cell population is selectively produced in the spleens of mice treated with anti-igd from birth .
