The antibody response to Plasmodium falciparum : cues for vaccine design and the discovery of receptor-based antibodies

Tan, Joshua ; Piccoli, Luca ; Lanzavecchia, Antonio

In: Annual Review of Immunology

P. falciparum remains a serious public health problem and a continuous challenge for the immune system due to the complexity and diversity of the pathogen. Recent advances from several laboratories in the characterization of the antibody response to the parasite have led to the identification of critical targets for protection and revealed a new mechanism of diversification based on the...

Magi1, a new potential tumor suppressor gene in estrogen receptor positive breast cancer

Alday-Parejo, Begoña ; Richard, François ; Wörthmüller, Janine ; Rau, Tilman ; Galván, José A. ; Desmedt, Christine ; Santamaria-Martinez, Albert ; Rüegg, Curzio

In: Cancers, 2020, vol. 12, no. 1, p. 223

Membrane-associated guanylate kinase (MAGUK) with inverted domain structure-1 (MAGI1) is an intracellular adaptor protein that stabilizes epithelial junctions consistent with a tumor suppressive function in several cancers of epithelial origin. Here we report, based on experimental results and human breast cancer (BC) patients’ gene expression data, that MAGI1 is highly expressed and acts...

How computational chemistry and drug delivery techniques can support the development of new anticancer drugs

Garofalo, Mariangela ; Grazioso, Giovanni ; Cavalli, Andrea ; Sgrignani, Jacopo

In: Molecules, 2020, vol. 25, no. 7, p. 22 p

The early and late development of new anticancer drugs, small molecules or peptides can be slowed down by some issues such as poor selectivity for the target or poor ADME properties. Computer-aided drug design (CADD) and target drug delivery (TDD) techniques, although apparently far from each other, are two research fields that can give a significant contribution to overcome these problems....

DNA (hydroxy)methylation in T helper lymphocytes

Monticelli, Silvia

In: Trends in biochemical sciences, 2019, vol. 44, no. 7, p. 589-598

Upon recognition of an antigen, the differentiation of antigen-inexperienced naïve T lymphocytes into subsets able to effectively coordinate host defense is controlled by a network of transcription factors and regulatory molecules. In the cell nucleus, these factors act in the context of epigenetic modifications that influence DNA accessibility and ultimately gene expression. This review...

TRPM7 kinase activity is essential for T cell colonization and alloreactivity in the gut

Romagnani, Andrea ; Vettore, Valentina ; Rezzonico-Jost, Tanja ; Hampe, Sarah ; Rottoli, Elsa ; Nadolni, Wiebke ; Perotti, Michela ; Meier, Melanie A. ; Hermanns, Constanze ; Geiger, Sheila ; Wennemuth, Gunther ; Recordati, Camilla ; Matsushita, Masayuki ; Muehlich, Susanne ; Proietti, Michele ; Chubanov, Vladimir ; Gudermann, Thomas ; Grassi, Fabio ; Zierler, Susanna

In: Nature communications, 2017, vol. 8, p. 1917

The melastatin-like transient-receptor-potential-7 protein (TRPM7), harbouring a cation channel and a serine/threonine kinase, has been implicated in thymopoiesis and cytokine expression. Here we show, by analysing TRPM7 kinase-dead mutant (Trpm7 R/R) mice, that the enzymatic activity of the receptor is not essential for thymopoiesis, but is required for CD103 transcription and gut-homing of ...

Label-free biosensor detection of endocrine disrupting compounds using engineered estrogen receptors

La Spina, Rita ; Ferrero, Valentina E. V. ; Aiello, Venera ; Pedotti, Mattia ; Varani, Luca ; Lettieri, Teresa ; Calzolai, Luigi ; Haasnoot, Willem ; Colpo, Pascal

In: Biosensors, 2018, vol. 8, no. 1, p. 1-15

Endocrine Disrupting Compounds (EDCs) are chemical substances shown to interfere with endogenous hormones affecting the endocrine, immune and nervous systems of mammals. EDCs are the causative agents of diseases including reproductive disorders and cancers. This highlights the urgency to develop fast and sensitive methods to detect EDCs, which are detrimental even at very low concentrations....
