Laboratory of Molecular Biology and Immunology
The Laboratory of Molecular Biology and Immunology was created in 2003. Today, it has three faculty members who participate in 5 undergraduate and 5 post-graduate courses and supervise the research work of three post-doctoral fellows, three postgraduate students and the diploma work of several undergraduate students.
We are in close collaboration with several Universities and Research Institutes, both national and international. We are performing research in aspects related to Immunology, Biochemistry, Molecular and Structural Biology, Genetics and Pharmacogenomics, which are funded from several research programs.

Molecular Biology & Neurobiology Group
(K. Poulas)

The group is working mainly on the human nicotinic acetylcholine receptors (AChRs) and on diseases in which these receptors are involved. AChRs are a family of membrane proteins located in many synapses, either in the nervous system (central and peripheral) or in the neuromuscular junctions, mediating neuromuscular transmission. Their importance in physiology and pathology and the fact that they have been extensively studied, renders the AChRs a model for neurotransmitter receptor molecules.

Research Activities/Expertise
Understanding the autoimmune disease Myasthenia Gravis; Heterologous expression of AChR domains; Structure and function of nAChR; Structural studies of the extracellular domains of human AchR’s; Mass production and purification of recombinant proteins; Crystallization and crystallographic analysis of proteins; Molecular modeling.

Genetics & Pharmacogenomics Group
(G. Patrinos)

Our long-term goal is to identify the genes involved in differentially increasing Hb F levels upon HU treatment in groups of β-thalassemia patients, categorized based on the levels of Hb F levels induction upon HU treatment in order to: (a) provide insights as to which genes and regulatory pathways are involved in the differentially elevated Hb F levels in the two groups of patients and (b) lead to the identification of new protein factors, which bind to the γ-globin promoter or other regulatory regions in the human β-globin gene locus, and hence are involved in the up- or down-regulation of the γ-globin genes expression, which will initiate further studies and larger-scale clinical trials to develop alternative β-thalassemia therapeutics. Similarly, we aim to identify putative pharmacogenetic markers to determine response to lithium treatment in bipolar disease patients.  Finally, we continue to pursue development of National/Ethnic genetic databases to document the vast genetic heterogeneity of various populations worldwide.
The group is in constant collaboration with the Erasmus University Medical Center (Rotterdam, the Netherlands), the University of Cagliari (Cagliari, Italy), the University of Athens, the University of Malta Medical School (Malta) and the Cyprus Institute of Neurology and Genetics (Nicosia, Cyprus).

Research Activities/Expertise

  • Pharmacogenomics of response to HU treatment in hemoglobinopathies patients
  • Pharmacogenomics of response to lithium treatment in bipolar disease patients
  • Developmental regulation of human fetal globin genes expression
  • Development of National/Ethnic genetic databases.
