Pertussis toxin other lung cells produce a variety of chemokines. PT has been found to inhibit the early transcription of keratinocyte-derived chemokine, macrophage inflammatory protein 2 and LPS-induced CXC chemokine. Eventually, PT causes lymphocytosis, one of the systemic manifestations of whooping cough. PT, a decisive virulence determinant of "B. pertussis", is able to cross the blood–brain barrier by increasing its permeability. As a result, PT can cause severe neurological complications; however, recently it has been found that the medicinal usage of "Pertussis" toxin can promote the development of regulatory T cells and prevent central nervous system autoimmune disease, such as multiple sclerosis.
