The aim of our study was to evaluate the efficacy of FK506, mycophenolate mofetil (MM) and aminoguanidine (AMG) on infiltration of macrophages (MPHs), neutrophils (NPHs) and dendritic cells (DC) into corneal grafts during the early phases after transplantation (Tx). Tx was performed in mice (C57BL/10 to BALB/c). Therapy included FK506 (0.2 mg/kg), MM (30 mg/kg) or AMG (0.1 g/kg), started at the day of Tx and was injected i.p. daily. Corneas were excised on the 3rd and 7th day after Tx. Immunohistological evaluation using antibodies against MPHs, NPHs and DC was performed and corneal grafts were assessed in the periphery and in central part of the cornea separately. On the 3rd day after Tx, a massive infiltration of MPHs and NPHs into corneal grafts was revealed; the DC in filtration was lower in all treated groups. Treatment with FK506 and MM led to a significant reduction of NPHs in the centers of the grafts, but not of MPHs. In contrast, AMG significantly reduced MPHs migration into allografts on the third day after Tx, whereas NPHs infiltration has not been attenuated. However, immunosuppressants had no influence on the infiltration of DC during early phases after Tx., P. Bysterská, P. Svozílková, H. Farghali., and Obsahuje bibliografii a bibliografické odkazy
Pokrok zejména v oblasti molekulární imunologie otevřel nové možnosti, umožnil identifikaci nových cílů v imunitním systému a vedl k vývoji nových protinádorových látek. Některé z těchto látek jsou v současné době schváleny a jsou součástí standardní léčby, další jsou v posledních fázích klinického zkoušení. Tyto látky mají význam zejména v paliativní indikaci u nemocných s pokročilým stadiem onemocnění, kterým nemůžeme nabídnout mnoho léčebných možností. Očekává se rozšíření imunoterapie i do indikace adjuvantní. Potenciál imunoterapie v léčbě nádorových onemocnění je velký, pozornost se soustřeďuje na solidní nádory. Zejména maligní melanom hrál důležitou roli při rozvoji imunoterapie u nádorových onemocnění. Značné úsilí je také věnováno hledání klinicky dostupných prediktivních a prognostických faktorů, které by dokázaly vybrat pacienty vhodné k léčbě a které by usnadnily její průběžné hodnocení., Advances, particularly in the field of molecular immunology, have opened new opportunities, allowed identification of new targets in the immune system, and resulted in developing new anticancer agents. Some of these agents have already been approved and become a part of standard treatment while others are in the final phases of clinical trials. These agents are of particular importance in the palliative indication in patients with advanced disease stage who cannot be offered many treatment options. Immunotherapy is expected to be approved for the extended adjuvant indication. The potential of immunotherapy in treating tumour disease is great, with attention being paid to solid tumours. It is malignant melanoma that has played an important role in developing immunotherapy in tumour diseases. Considerable effort is being made to search for clinically available predictive and prognostic factors capable of selecting patients suitable for treatment and facilitating its continuous evaluation., Denisa Vitásková, Bohuslav Melichar, and Literatura
