    Role of mTOR in the activation of marginal zone B cells by TACI 

    Gentile, Maurizio (Date of defense: 2014-09-19)

    The marginal zone (MZ) of the spleen contains an innate-like subset of B cells that mount rapid protective antibody responses to polysaccharides and lipids from bloodborne viruses and bacteria. These antigens activate ...

    The Role of mutational processes in the evolution of somatic tissues and malignancy 

    Pich Roselló, Oriol (Date of defense: 2021-03-24)

    Cells of our body are constantly exposed to events that can create lesions in the DNA. If unremoved by the DNA repair mechanisms, the lesion may lead to a mutational event. Some of these events might drive the transformation ...

    Role of network topology based methods in discovering novel gene-phenotype associations 

    Güney, Emre (Date of defense: 2012-09-25)

    The cell is governed by the complex interactions among various types of biomolecules. Coupled with environmental factors, variations in DNA can cause alterations in normal gene function and lead to a disease condition. ...

    Role of NFAT5 in macrophage polarisation 

    Tellechea Recarte, Mónica (Date of defense: 2017-05-19)

    Macrophages are exquisite sensors of tissue homeostasis that can rapidly switch between pro- and anti-inflammatory or regulatory modes to respond to perturbations in the microenvironment. This functional plasticity involves ...

    Role of NK cells in the efficacy of anti-HER2 therapeutic antibodies in breast cancer : from biomarkers to functional checkpoints enhacing ADCC responses 

    Cabo, Mariona (Date of defense: 2019-11-08)

    HER2 overexpression accounts for approximately 15-20% of breast tumors, and mainstay therapy for these patients includes HER2-specific antibodies in combination with chemotherapy. Although the efficacy of anti-HER2 antibodies ...

    Role of NTRK3 in the extinction of fear memories and streess-coping: studies in a mouse model of panic disorder 

    Amador Arjona, Alejandro (Date of defense: 2008-07-23)

    The correct development and function of CNS is critical for brain health of the organism. Early or chronic stress causes prominent alterations in brain function, and affects the expression of neurotrophic factors in limbic ...

    Role of PLK1 in steroid hormone signaling in breast cancer cells 

    Wierer, Michael (Date of defense: 2013-01-13)

    Steroid receptors (SRs) are hormone-induced transcription factors that regulate gene expression by their concerted actions with coregulatory proteins. Performing a quantitative mass spectrometry-based interaction screen ...

    Role of polycomb-like proteins in mouse embryonic stem cell differentiation 

    Condemi, Livia (Date of defense: 2024-03-07)

    Polycomb repressive complex (PRC) 2 is one of the key regulators of the transcriptional programs, it maintains stem cell properties and guides cell lineage specification. It is a multiprotein complex formed by a core and ...

    Role of PRC2-associated factor EPOP in mouse embryonic stem cells differentiation and early development 

    Chammas, Paul (Date of defense: 2019-11-29)

    Polycomb repressive complex 2 (PRC2) is a key epigenetic regulator of gene expression. It acts through its histone-modifying activity, as it is responsible of di- and trimethylating the tail of histone H3 on lysine 27 ...
