It is important to note that while our data are unlike those found in the study by Wigelsworth et al. [36], where they found CD44 expression promotes iota intoxication in Vero (African green monkey kidney) and human melanoma (RPM) cell cultures (in vitro), as well as in mice (in vivo lethality), the authors state that the cells they used contained LSR. Here, CD44 is linked to melanoma.
