Neurotoxic autoantibodies mediate congenital cortical impairment of offspring in maternal lupus

Children born to mothers with lupus have a higher rate of learning disorders. Now, in mouse studies, Betty Diamond and her colleagues show that neurotoxic antibodies found in mothers with lupus are transferred to the brains of their offspring. This leads to abnormalities in cortical formation during development and in cognitive function when the pups become adults.
