tokens: By using 70Z/3-derived pre-B-cell lines either lacking or expressing human CD14 ( the LPS receptor ) , it was observed that expression of human CD14 imparted responsiveness to LPS but not to OspA or spirochetal lipopeptides ( assessed by induction of NF-kappa B and expression of surface immunoglobulin M ) .
