The host adherens junction molecule nectin-1 is down regulated in Chiamydia trachomatis-infected genital epithelial cells.

The article reports on the Yersinia pestis, a causative agent of bubonic plague, excrete L-aspartic acid at the expense of exogenous L-glutamic acid during expression of the low-calcium response. It discusses that the results of enzymic analysis provided suggest that a previously defined deficiency of aspartese (AspA) accounts for the phenomenon rather than an elevated oxaloacetate pool. It infers that the only known distinction between most sequenced isolates of aspA from Y. A study on the Yersinia pestis is presented.
