mTORC1 Inhibition Protects Human Regulatory T Cells From Granzyme-B-Induced Apoptosis.

Front Immunol 2022 10;13:899975. Epub 2022 Jun 10.

Transplantation Research Center, Division of Nephrology, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, United States.

Regulatory T cells (T) have shown great promise as a means of cellular therapy in a multitude of allo- and auto-immune diseases-due in part to their immunosuppressive potency. Nevertheless, the clinical efficacy of human T in patients has been limited by their poor homeostasis. To avert apoptosis, T require stable antigenic (CD3ζ/T-cell-receptor-mediated), co-stimulatory (CD28-driven), and cytokine (IL-2-dependent) signaling. Read More

Inhibition of miR-let-7i Induces DC Immature Cells and Improves Skin Graft Tolerance.

Dis Markers 2022 15;2022:8605621. Epub 2022 Jun 15.

Hepatopancreatobiliary Surgery Department 1, The Second Affiliated Hospital of Kunming Medical University, 650101 Kunming, China.

Dendritic cells (DC) initiate the immune response in the body. They can stimulate T cell activation, proliferation, and differentiation and ultimately participate in the immune response and the immune tolerance response. The purpose of this study was to coculture DCs and T cells and subcutaneously inject DCs transfected with miR-let-7i into rhesus monkey transplantations to verify the role of miR-let-7i in allograft immune tolerance.

Novel Complement C5 Small-interfering RNA Lipid Nanoparticle Prolongs Graft Survival in a Hypersensitized Rat Kidney Transplant Model.

Transplantation 2022 Jun 24. Epub 2022 Jun 24.

Department of Urology, Tokyo Women's Medical University, Shinjuku-ku, Tokyo, Japan.

Background: Prophylaxis of antibody-mediated rejection (AMR) caused by donor-specific antibodies remains challenging. Given the critical roles of complement activity in antibody-mediated graft injury, we developed a lipid nanoparticle (LNP) formulation of small-interfering RNA against complement C5 (C5 siRNA-LNP) and investigated whether C5 siRNA-LNP could downregulate the complement activity and act as an effective treatment for AMR.

Methods: Lewis recipient rats were sensitized by skin grafting from Brown Norway donor rats. Read More

Association of polymorphous light eruption with NOD-2 and TLR-5 gene polymorphisms.

J Eur Acad Dermatol Venereol 2022 Jun 24. Epub 2022 Jun 24.

Department of Dermatology, University Hospital Regensburg, D-93042, Regensburg, Germany.

Background: Polymorphous light eruption (PLE) is a common, immunologically mediated, photosensitive skin disease. After ultraviolet-B (UV-B) irradiation, patients with PLE show reduced Langerhans cell (LC) depletion in the epidermis, which results in a non-suppressive microenvironment in the skin. Interestingly, severe acute graft-versus-host-disease (aGvHD) occurred in stem cell transplanted patients that showed no or incomplete depletion of LCs after UVB-irradiation. Read More

Free Skin Grafting to Reconstruct Donor Sites after Radial Forearm Flap Harvesting: A Prospective Study with Platelet-Rich Fibrin (PRF).

J Clin Med 2022 Jun 17;11(12). Epub 2022 Jun 17.

Department of Oral and Maxillofacial Plastic Surgery, University Hospital Würzburg, Pleicherwall 2, 97070 Würzburg, Germany.

Reconstruction of the donor site after radial forearm flap harvesting is a common procedure in maxillofacial plastic surgery. It is normally carried out with split-thickness or full-thickness free skin grafts. Unfortunately, free skin graft transplantation faces wound healing impairments such as necrosis, (partial) graft loss, or tendon exposure. Read More

Identifying Candidates for Immunotherapy among Patients with Non-Melanoma Skin Cancer: A Review of the Potential Predictors of Response.

J Clin Med 2022 Jun 11;11(12). Epub 2022 Jun 11.

Dermatology Clinic, Maggiore Hospital, University of Trieste, 34125 Trieste, Italy.

Background: Non-melanoma skin cancer (NMSC) stands as an umbrella term for common cutaneous malignancies, including basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC), together with rarer cutaneous cancers, such as Merkel cell carcinoma (MCC) and other forms of adnexal cancers. The majority of NMSCs can be successfully treated with surgery or radiotherapy, but advanced and metastatic stages may require systemic approaches such as immunotherapy with immune checkpoint inhibitors (ICIs).

Summary: Since immunotherapy is not effective in all patients and can potentially lead to severe adverse effects, an important clinical question is how to properly identify those who could be suitable candidates for this therapeutic choice. Read More

Department of Oncology-Pathology, Karolinska Institutet, Stockholm, Sweden

Background: Adoptive cell therapy using cytotoxic lymphocytes is an efficient immunotherapy against solid and hematological cancers. However, elevated levels of reactive oxygen species (ROS) in the hostile tumor microenvironment can impair NK cell and T cell function. Auranofin, a gold (I)-containing phosphine compound, is a strong activator of the transcription factor Nrf2. Read More

The U-Turn Tournedos (UTT) Flap: A Technical Surgical Evolution for Deep Complex Calvarial Defects.

J Craniofac Surg 2022 May;33(3):935-938

Division of Plastic and Reconstructive Surgery, MUHC, McGill University, Montreal, QC, Canada.

Abstract: Patients treated for complex oncological calvarial defects are at a higher risk of severe complications (38%): infection, meningitis, dehiscence, and hardware/brain exposure. The patient cohorts at our center have led to the development of the "U-Turn" technical (UTT) addition of our previously reported turnover "tournedos" myocutaneous latissimus dorsi free flap. This allows for an improved ability to fill these large, round, complex defects, maintaining the safety of our original surgical technique, while improving aesthetic outcomes. Read More

Resurfacing of Face and Neck Using Superthin Thoracodorsal Artery Perforator Free Flaps.

J Craniofac Surg 2022 May 1;33(3):931-934. Epub 2021 Oct 1.

Department of Plastic and Reconstructive Surgery, College of Medicine, Hanyang University, Seoul, South Korea.

Background: Resurfacing of facial and neck defects is challenging due to the unique skin color, texture, and thickness of the region. With the development of microsurgical reconstruction, perforator- free flaps can provide adequate soft tissue. However, despite various modifications, such flaps hardly satisfy cosmetic requirements, due to differences in color and bulkiness. Read More

Local Pterional Advancement Flap: A Minimally Invasive Option to Reconstruct Spheno-Temporal Extracranial Soft Tissues Dehiscences in Fragile Patients.

J Craniofac Surg 2022 May 3;33(3):910-912. Epub 2021 Aug 3.

Department of Neurosurgery and Gamma Knife Radiosurgery.

Background: Late-onset, extracranial soft tissues dehiscence in the spheno-temporal region after major neurosurgical procedures might represent a potentially life-threatening complication.Due to surgery-related galeal/pericranial and myofascial temporal atrophy, classical regional flaps are often unavailable, enforcing potential indication for free vascularized flaps.Nevertheless, in elderly multioperated patients, who are not eligible for major surgery, it becomes mandatory to consider less invasive options for reconstruction.
