E., Gröne, H.-J., Schlöndorff, D., Anders, H.-J.: Chemokine receptor CCR1 but not CCR5 mediates leukocyte recruitment and subsequent renal fibrosis after unilateral ureteral obstruction. J Am Soc Nephrol, 15, 2004; 2: 337-347. We examined the role of chemokine receptor CCR1 and CCR5 in renal inflammatory infiltrate and subsequent interstitial fibrosis. Unilateral ureteral obstruction model in mice deficient for CCR1 or CCR5 was used for experiments. Analysis of UUO kidneys from CCR1-deficient mice or BX471 treated mice revealed a reduction of interstitial macrophages and lymphocytes compared with wild type controls. In contrast, renal leukocytes and fibrosis were unaffected in CCR5-deficient mice with UUO. Interstitial fibroblasts, renal TGF-β1 mRNA expression, interstitial volume and collagen I depositions were significantly reduced in CCR1-deficient mice. Lack of CCR5 does not affect renal fibrosis after UUO. Thus, CCR1 but not CCR5 is required for leukocyte recruitment and fibrosis after UUO in mice.

Chick Embryo as a Model for the Study of Pancreas during Normal and Experimental Conditions
Maňáková, Eva ; Jelínek, Richard (advisor) ; Peterka, Miroslav (referee) ; Zemanová, Zdeňka (referee)
The aim was to describe changes in the volume of endocrine cells during pancreas development, try to estimate the proliferative activity and ultrastructural characterize cells that are responsible for the growth of pancreatic tissue during the prenatal period. Using chicken embryo represents a simple model on which it would be possible to evaluate the results of the experimental effect of external influences (teratogen) on the development of the pancreas. It allows simplification of the experimental conditions simulating ex. diabetes mothers. The aim was to demonstrate that the trend growth of endocrine tissue in both models (mammal, bird) is like and therefore this model can be used even if metabolism of birds differs from mammals.
