Senescence of fibroblastic reticular cells in draining lymph nodes: immunoregulation following transplantation.

J Clin Invest 2020 Jun 29. Epub 2020 Jun 29.

The lymph node (LN) is an intriguing site not only for inducing protective effector immunity but also for inducing tolerance against peripherally encountered antigens such as tissue-specific self-antigens that are regionally drained and through draining lymph nodes (DLNs). The dual functions of DLNs in immunity are attributable at least in part to fibroblastic reticular cells (FRCs), which are a major population of the nonhematopoietic compartment in the LN. In this issue of the JCI, Li, Zhao, and colleagues investigated DLNs in the transplantation setting. Read More

Mesenchymal stem cells (MSCs) are capable of differentiating into a limited number of diverse cells and secrete regenerative factors that contribute to the repair of damaged tissue. In response to signals emitted by tissue damage, MSCs migrate from the bone marrow and area surrounding blood vessels within tissues into the circulating blood, and accumulate at the site of damage. Hence, MSC transplantation therapy is beginning to be applied to the treatment of various intractable human diseases. Read More

Diagnostics (Basel) 2020 Jun 22;10(6). Epub 2020 Jun 22.

Department of Emergency and Organ Transplantation, University of Bari "Aldo Moro", Piazza G. Cesare 11, 70124 Bari, Italy.

Among all melanomas, the mucosal type is very rare and may occur in the sino-nasal mucosa, vagina, anus and the oral cavity. At variance with melanomas of the skin, no risk factors, such as familiarity, UV-exposure and skin phenotype, have been clearly identified for such neoplasms. Frequently, the diagnosis is delayed and achieved at advanced stages or when metastases have already occurred. Read More

Reconstruction of Full Thickness Calvarial Defect With Dermal Regeneration Template and Full Thickness Skin Graft After Encephaloduroarteriosynangiosis.

J Craniofac Surg 2020 Jun 15. Epub 2020 Jun 15.

Department of Surgery, Division of Plastic and Reconstructive Surgery, University of Wisconsin School of Medicine and Public Health, Madison, WI.

Full-thickness defects of the calvarium often present reconstructive challenges, necessitating large rotational flaps or microsurgical free tissue transfer. Although the vascularity of the scalp is robust, there is an increased risk of wound healing complications after both direct and indirect intracranial revascularization procedures as compared to routine craniotomies, as these procedures utilize extracranial scalp vasculature to supply the ischemic brain. Patients presenting with wound healing complications following intracranial revascularization surgeries may not be candidates for extensive reconstructive procedures, as they are often medically comorbid with cardiac disease, diabetes, and a paucity of recipient vessels for free tissue transfer due to underlying vascular disease that prompts initial revascularization surgery.
