Study of sperm proteins in modelspecies of chondrostean and teleostean fish
Koubek, Pavel ; Elzeinová, Fatima ; Linhart, O. ; Pěknicová, Jana
Specific in the study of fish reproduction is outer fertilization. spermatozoa are usually expelled into host medium of the outer encironment. The cells have to cope with an extremely different encironment and their protection against the outer environment is much weaker than that of oocytes. The way of fertilization also differs from mammalian fertilization.
Regulation and localization of sperm akaps during capacitation, activation, induced acrosomal reaction and binding to the oocyte
Kyselová, Vendula ; Pěknicová, Jana
Recent evidence suggests that the cAMP-dependent protein kinase A (PKA) is localized to specific subcellulatr compatrments trought association with A Kinase Anchoring Proteins (AKAPs). The AKAPs now represent a functionally related family of regulatory proteins containing a conserved PKA binding domain and a unique targeting sequence that direct the PKA-AKAP complex to subcellular structures.
Multigenerational study - effect of the selected compounds on the mouse fertility
Boubelík, Michael ; Pěknicová, Jana ; Kyselová, Vendula ; Buckiová, D.
Several compounds known to be effective for their influence onto the environment were tested. Compounds tested in this study were: benzo/a/ pyrene, lindane (hexachlorocyclohexane isomer), 4-n-nonylphenol, bisphenol A and octachlorostyrene. The question was if these compounds might also function as endocrine disruptors.
Estimation of the post-meiotic state of spermatogenesis in man by immunofluorescence with monoclonal antibodies against intra-acrosomal sperm proteins
Chládek, David ; Pěknicová, Jana
Male infertility due to severe azoospermia has been associated with the absence of spermatozoa in ejaculated. We tested the ejaculates (IVF latoratory Pranatal Ltd) from 30 patients with azoospermia for the presence of cells from defferent stages of spermiogenesis. Monoclonal sntibodews against intraacrosomal human sperm proteins were used in the immunofluorescence test for detection of acrosomal proteins in the acrosomal precursors and acrosomes.

Iscare IVF a.s. had a long record of successful azoospermic treatment since 1997, when the first pregnancies by MESA a TESE were published in the Czech republic. A series of diferent implanted laboratory techniques supported good results from last year. The medical problem is solved during the other field of application-histlogical findings and immunofluorescent methods.
Antitrophoblast cell-mediated immunity /AT-CMI/ in recurrent miscarriage and ectopic pregnacy
Madar, J. ; Kučera, E. ; Šůla, K. ; Chaloupková, A. ; Pěknicová, Jana ; Tolarová, M. ; Nouza, K. ; Kinský, R.
Specific mechanisms operate in decidua nad trophoblast to establish and maintain immunological tolerance of the embryo in mother's uterus. due to the lack of this tolerance, disturbances of pregnancy may result. In this presentation, we have tested the hypothesis that anti-trohhoblast cell-mediated immunity (AT-CMI) is elevated in habitually aborting women and that extra-uterine localisation of the embryo leads to subsequent elevation of AT-CMI.
Monoklonální protilátky proti proteinům savčích spermií jako nástroj pro studium fertilizace

Monoklonální protilátky proti proteinům savčích spermií jako nástroj pro studium fertilizace.
Fertilization-related surface and intra-acrosomal antigens of mammalian spermatozoa. Application of monoclonal antibodies against sperm proteins in veterinary and human medicine
Pěknicová, Jana ; Jonáková, Věra
The role of cell-surface proteins, which belong to family of spermadhesins, and intra-acrosomal proteins of spermatozoa in binding sperm to the glycoprotein network of zona pellucida of oocytes were studied and results were presented.
