2. Biotic / Abiotic Stress Influences on Human Epidermal Keratinocyte Cells

Seyed Mohammad Motevalli; Fateme Mirzajani

Volume 2, Issue 2 , Spring 2019, Pages 53-58

Abstract
  Human epidermal keratinocyte cells are the first defence blocks against the aggressive agents such as pathogens and xenobiotic materials. Synthesis process of the cellular proteins can be affected by abiotic stresses (aBS like: SiO2 nanoparticles) and biotic stresses (BS like: Virus), leading to the ...  Read More
