WebUnsuccessful wound closure in chronic wounds can be linked to altered keratinocyte activation and their inability to re-epithelize. Suggested mechanisms driving this impairment involve unbalanced cytokine signaling. However, the molecular events leading to these aberrant responses are poorly understood. Among cytokines affecting keratinocyte … WebHá 2 dias · Around the world, climate change is impacting all forms of life, including microbiomes (see Glossary). As the engines of Earth’s biogeochemical cycles [1], microbiomes can alter global carbon and nutrient cycling as the environment changes. Given that soils hold nearly 2000 Pg carbon [2], the climate responses of soil microbiomes …
