41. NK cells are known for their ability to eradicate tumor cells without any prior sensitization to them. 42. Furthermore, they may be used in in vivo acute toxicity tests of dermal irritation and sensitization . 43. Priming and sensitization played a large part in losses; no strong correlation with habituation was found. 44. This antigen sensitization and subsequent incompatibility phenomenon causes Rhesus disease, the most common form of HDN. 45. Chemical sensitization ( e . g ., sulfur plus gold sensitization ) is applied on the surface. 46. Chemical sensitization ( e . g ., sulfur plus gold sensitization ) is applied on the surface. 47. It has been observed that this type of dermatitis does not require prior sensitization of the immune system. 48. This is due to local skin memory T-cells, which remain in the original sensitization site. 49. Phosphorylation of TRPV1 by protein kinase C have been shown to play a role in sensitization of TRPV1. 50. C fibers cause central sensitization of the dorsal horn in the spinal cord in response to their hyperactivity.
