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...

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...

Proteasomal and lysosomal clearance of faulty secretory proteins : ER-associated degradation (ERAD) and ER-to-lysosome-associated degradation (ERLAD) pathways

Fregno, Ilaria ; Molinari, Maurizio

In: Critical reviews in biochemistry and molecular biology, 2019, vol. 54, no. 2, p. 153-163

About 40% of the eukaryotic cell’s proteins are inserted co- or post-translationally in the endoplasmic reticulum (ER), where they attain the native structure under the assistance of resident molecular chaperones and folding enzymes. Subsequently, these proteins are secreted from cells or are transported to their sites of function at the plasma membrane or in organelles of the secretory and ...

Structural basis for broad HIV-1 neutralization by the MPER-specific human broadly neutralizing antibody LN01

Pinto, Dora ; Fenwick, Craig ; Caillat, Christophe ; Silacci, Chiara ; Guseva, Serafima ; Dehez, François ; Chipot, Christophe ; Barbieri, Sonia ; Minola, Andrea ; Jarrossay, David ; Tomaras, Georgia D. ; Shen, Xiaoying ; Riva, Agostino ; Tarkowski, Maciej ; Schwartz, Olivier ; Bruel, Timothée ; Dufloo, Jérémy ; Seaman, Michael S. ; Montefiori, David C. ; Lanzavecchia, Antonio ; Corti, Davide ; Pantaleo, Giuseppe ; Weissenhorn, Winfried

In: Cell host & microbe, 2019, vol. 26, no. 5, p. p. 623-637.e8

Potent and broadly neutralizing antibodies (bnAbs) are the hallmark of HIV-1 protection by vaccination. The membrane-proximal external region (MPER) of the HIV-1 gp41 fusion protein is targeted by the most broadly reactive HIV-1 neutralizing antibodies. Here, we examine the structural and molecular mechansims of neutralization by anti-MPER bnAb, LN01, which was isolated from lymph-node-derived...

SHP-2 in lymphocytes’ cytokine and inhibitory receptor signaling

Niogret, Charlène ; Birchmeier, Walter ; Guarda, Greta

In: Frontiers in immunology, 2019, vol. 10, no. 2468, p. 1-11

Somewhat counterintuitively, the tyrosine phosphatase SHP-2 (SH2 domain- containing protein tyrosine phosphatase-2) is crucial for the activation of extracellular signal-regulated kinase (ERK) downstream of various growth factor receptors, thereby exerting essential developmental functions. This phosphatase also deploys proto-oncogenic functions and specific inhibitors have recently been ...
