TL;DR: The manner in which studies of models of liver fibrosis have contributed to the paradigm of dynamic wound healing in this solid organ is highlighted.
Abstract: Models of liver fibrosis, which include cell culture models, explanted and biopsied human material, and experimental animal models, have demonstrated that liver fibrosis is a highly dynamic example of solid organ wound healing. Recent work in human and animal models has shown that liver fibrosis is potentially reversible and, in specific circumstances, demonstrates resolution with a restoration of near normal architecture. This Review highlights the manner in which studies of models of liver fibrosis have contributed to the paradigm of dynamic wound healing in this solid organ.
TL;DR: Findings implicate perivascular Gli1(+) MSC-like cells as a major cellular origin of organ fibrosis and demonstrate that these cells may be a relevant therapeutic target to prevent solid organ dysfunction after injury.
TL;DR: Without some form of prevention, CMV infection primarily occurs in the first 3 months following transplant, and onset may be delayed in patients receiving CMV prophylaxis.
TL;DR: Solid organ transplantations save lives in patients affected by terminal organ failures and improve quality of life, and are increasingly challenged by the growing proportion of elderly transplant patients with comorbidities.
Abstract: Solid organ transplantations save lives in patients affected by terminal organ failures and improve quality of life. Organ transplantations have gradually ameliorated in the last two decades and usually provide excellent results in children and young adults, and are increasingly challenged by the growing proportion of elderly transplant patients with comorbidities. Renal transplantation increases patient survival over dialysis, and lifesaving transplants are indispensible to treat patients with liver, heart, or lung irreversible diseases. Solid organ transplant programs activity has been steadily growing but is still far from global needs, with great differences among countries. Solid organ transplantations are essential for developed and mature health care systems.
