Homeotic regulation of segment-specific differences in neuroblast numbers and proliferation in the Drosophila central nervous system.
Prokop A, Bray S, Harrison E, Technau GM. Prokop A, et al. Mech Dev. 1998 Jun;74(1-2):99-110. doi: 10.1016/s0925-4773(98)00068-9. Mech Dev. 1998. PMID: 9651493
We show that the homeotic genes Ultrabithorax and abdominal-A regulate these late differences, and that misexpression of either gene in thoracic neuroblasts after segregation is sufficient to induce abdominal behaviour. However, in wild type embryos we only detect abdomina …

The origin of postembryonic neuroblasts in the ventral nerve cord of Drosophila melanogaster.
Prokop A, Technau GM. Prokop A, et al. Development. 1991 Jan;111(1):79-88. Development. 1991. PMID: 1901786
Furthermore, BrdU labelling suggests that the embryonic neuroblast itself rather than one of its progeny resumes proliferation as a postembryonic neuroblast. A second type of clone consists of embryonic progeny only....

Early tagma-specific commitment of Drosophila CNS progenitor NB1-1.
Prokop A, Technau GM. Prokop A, et al. Development. 1994 Sep;120(9):2567-78. Development. 1994. PMID: 7956832
., Prokop, A., Bossing, T. and Technau, G. M. (1993) Development 118, 765-775). Here, we demonstrate by heterotopic transplantations that tagma specificity of NB1-1 is determined in the neuroectoderm at the early gastrula stage (stage 7). ...Heat induction of Ubx or …

A common precursor for glia and neurons in the embryonic CNS of Drosophila gives rise to segment-specific lineage variants.
Udolph G, Prokop A, Bossing T, Technau GM. Udolph G, et al. Among authors: prokop a. Development. 1993 Jul;118(3):765-75. Development. 1993. PMID: 8076516
In this study, we present the complete embryonic lineage of a neuroectodermal precursor in Drosophila that gives rise to neurons as well as glia in the abdominal CNS. ...Thus, in addition to neuroblasts and glioblasts, there exists a third class of CNS precursors in …

Normal function of the mushroom body defect gene of Drosophila is required for the regulation of the number and proliferation of neuroblasts.
Prokop A, Technau GM. Prokop A, et al. Dev Biol. 1994 Feb;161(2):321-37. doi: 10.1006/dbio.1994.1034. Dev Biol. 1994. PMID: 8313986
In the developing central nervous system of Drosophila, proliferation follows a reproducible and well-described spatial and temporal pattern. This pattern involves a defined number and distribution of neural stem cells (neuroblasts), as well as a precisely re …

Absence of PS integrins or laminin A affects extracellular adhesion, but not intracellular assembly, of hemiadherens and neuromuscular junctions in Drosophila embryos.
Prokop A, Martín-Bermudo MD, Bate M, Brown NH. Prokop A, et al. Dev Biol. 1998 Apr 1;196(1):58-76. doi: 10.1006/dbio.1997.8830. Dev Biol. 1998. PMID: 9527881
It is also required for adhesion of muscle HAJs to a less electron dense form of extracellular matrix, the basement membrane. ...We suggest that neuromuscular contact in part requires basement membrane adhesion to the general muscle surface, and this form of adhesion is co …

The kakapo mutation affects terminal arborization and central dendritic sprouting of Drosophila motorneurons.
Prokop A, Uhler J, Roote J, Bate M. Prokop A, et al. J Cell Biol. 1998 Nov 30;143(5):1283-94. doi: 10.1083/jcb.143.5.1283. J Cell Biol. 1998. PMID: 9832556 Free PMC article.

Integrating bits and pieces: synapse structure and formation in Drosophila embryos.
Prokop A. Prokop A. Cell Tissue Res. 1999 Aug;297(2):169-86. doi: 10.1007/s004410051345. Cell Tissue Res. 1999. PMID: 10470487 Review.
In order to build a functional network each neuron has to establish contacts with appropriate target cells, and at these contacts synapses of the right quality and strength have to be formed. Gaining insight into the mechanisms underlying this complex development is an imp …

Compartmentalization of central neurons in Drosophila: a new strategy of mosaic analysis reveals localization of presynaptic sites to specific segments of neurites.
Löhr R, Godenschwege T, Buchner E, Prokop A. Löhr R, et al. Among authors: prokop a. J Neurosci. 2002 Dec 1;22(23):10357-67. doi: 10.1523/JNEUROSCI.22-23-10357.2002. J Neurosci. 2002. PMID: 12451135 Free PMC article.
Synaptogenesis in the CNS has received far less attention than the development of neuromuscular synapses, although only central synapses allow the study of neuronal postsynaptic mechanisms and display a greater variety of structural and functional features. ...Second, we a …

In developing Drosophila neurones the production of gamma-amino butyric acid is tightly regulated downstream of glutamate decarboxylase translation and can be influenced by calcium.
Küppers B, Sánchez-Soriano N, Letzkus J, Technau GM, Prokop A. Küppers B, et al. Among authors: prokop a. J Neurochem. 2003 Mar;84(5):939-51. doi: 10.1046/j.1471-4159.2003.01554.x. J Neurochem. 2003. PMID: 12603819
This timeline is almost unchanged when the GABA synthetase glutamate decarboxylase (GAD) is strongly misexpressed throughout the nervous system suggesting a tight post-translational regulation of GABA expression. ...Our results provide the basis for investigations of genet …
