Crossover or non-crossover outcomes : tailored processing of homologous recombination intermediates

Sanchez, Aurore ; Reginato, Giordano ; Cejka, Petr

In: Current opinion in genetics & development, 2021, vol. 71, p. 39-47

DNA breaks may arise accidentally in vegetative cells or in a programmed manner in meiosis. The usage of a DNA template makes homologous recombination potentially error-free, however, recombination is not always accurate. Cells possess a remarkable capacity to tailor processing of recombination intermediates to fulfill a particular need. Vegetatively growing cells aim to maintain genome...

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...

Antibody-guided vaccine design : identification of protective epitopes

Lanzavecchia, Antonio ; Frühwirth, Alexander ; Perez, Laurent ; Corti, Davide

In: Current opinion in immunology, 2016, vol. 41, no. August, p. 62-67

In the last decade, progress in the analysis of the human immune response and in the isolation of human monoclonal antibodies have provided an innovative approach to the identification of protective antigens which are the basis for the design of vaccines capable of eliciting effective B-cell immunity. In this review we illustrate, with relevant examples, the power of this approach that can...

Thioredoxin-related transmembrane proteins : TMX1 and little brothers TMX2, TMX3, TMX4 and TMX5

Guerra, Concetta ; Molinari, Maurizio

In: Cells, 2020, vol. 9, no. 9, p. 11 p

The endoplasmic reticulum (ER) is site of synthesis and maturation of membrane and secretory proteins in eukaryotic cells. The ER contains more than 20 members of the Protein Disulfide Isomerase (PDI) family. These enzymes regulate formation, isomerization and disassembly of covalent bonds between cysteine residues. As such, PDIs ensure protein folding, which is required to attain functional...

Mitochondrial sphingosine-1-phosphate lyase is essential for phosphatidylethanolamine synthesis and survival of Trypanosoma brucei

Dawoody Nejad, Ladan ; Stumpe, Michael ; Rauch, Monika ; Hemphill, Andrew ; Schneiter, Roger ; Bütikofer, Peter ; Serricchio, Mauro

In: Scientific Reports, 2020, vol. 10, no. 1, p. 8268

Sphingosine-1-phosphate is a signaling molecule involved in the control of cell migration, differentiation, survival and other physiological processes. This sphingolipid metabolite can be degraded by the action of sphingosine-1-phosphate lyase (SPL) to form hexadecenal and ethanolamine phosphate. The importance of SPL-mediated ethanolamine phosphate formation has been characterized in only...

The MRE11 complex : a versatile toolkit for the repair of broken DNA

Reginato, Giordano ; Cejka, Petr

In: DNA repair, 2020, vol. 91–92, no. July–August, p. 13 p

When DNA breaks, the ends need to be stabilized and processed to facilitate subsequent repair, which can occur by either direct but error-prone end-joining with another broken DNA molecule or a more accurate homology-directed repair by the recombination machinery. At the same time, the presence of broken DNA triggers a signaling cascade that regulates the repair events and cellular progression...

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....
