Tebentafusp in the treatment of metastatic uveal melanoma - the first patient treated in the Czech Republic.

Background: Uveal melanoma is a rare cancer, in which metastases occur in approximately one half of cases. In metastatic disease, the prognosis is unfavorable and the median of survival does not exceed 6 months. Effective treatment options were very limited up to date.

Angiomodulators in cancer therapy: New perspectives.

The formation of new blood vessels plays a crucial for the development and progression of pathophysiological changes associated with a variety of disorders, including carcinogenesis. Angiogenesis inhibitors (anti-angiogenics) are an important part of treatment for some types of cancer. Some natural products isolated from marine invertebrates have revealed antiangiogenic activities, which are diverse in structure and mechanisms of action.

Thiazolidinediones Regulate the Level of ABC Transporters Expression on Lung Cancer Cells.

ATP binding cassette (ABC) transporters related to multidrug resistance (MDR) actively efflux various xenobio-tics from the cells across the cell membrane and decrease a drugs efficiency. Lung cancer is the leading cause of death among all types of cancer in the Czech Republic, and its incidence is still rising. Ciglitazone, rosiglitazone and troglitazone belonging to PPARγ agonist family (formerly used in diabetes mellitus treatment) were selected to investigate their capability to influence expression of ABC transporters on lung cancer cells.

[The Role of Regulatory T-cells in Antitumor Immune Response].

Regulatory T-lymphocytes (Treg) are essential for regulation of immune homeostasis and prevention of autoimmune disease development. Regulatory T-cells prevent the onset of autoimmune diseases; they keep immune homeostasis and modulate immune response during infection. Their activity is precisely controlled.

Cell Labeling and Targeting with Superparamagnetic Iron Oxide Nanoparticles.

Targeted delivery of cells and therapeutic agents would benefit a wide range of biomedical applications by concentrating the therapeutic effect at the target site while minimizing deleterious effects to off-target sites. Magnetic cell targeting is an efficient, safe, and straightforward delivery technique. Superparamagnetic iron oxide nanoparticles (SPION) are biodegradable, biocompatible, and can be endocytosed into cells to render them responsive to magnetic fields.
