Abstract Mutations in SH2D1A resulting in lack of SLAM-associated protein (SAP) expression cause the human genetic immunodeficiency X-linked lymphoproliferative disease. A severe block in germinal center development and lack of long-term humoral immunity is one of the most prominent phenotypes of SAP− mice. We show, in...
10.1038/nri2456
This paper, along with reference 25, provides the first evidence that germinal-centre defects that are associated with SAP deficiency result from a distinct signalling pathway that depends less on the ability of SAP to recruit molecules, including FYN, through its arginine 78 motif.

Abstract In primary human T cells, anergy induction results in enhanced p59Fyn activity. Because Fyn is the kinase primarily responsible for the phosphorylation of PAG (the phosphoprotein associated with glycosphingolipid-enriched microdomains), which negatively regulates Src-kinase activity by recruiting Csk (the C-te...

The authors show that PAG interacts with negative regulators of T cell signalling, including CSK, in primary human T cells and that knocking down PAG with siRNA enhances SFK activity and RAS activation.

Loss of the phosphatase PTPN22 enhances the functions of both effector and regulatory T cells.
10.1038/nri3403
Mice that lack PTPN22 were shown to have increased numbers of T Reg cells with enhanced function, which were capable of restraining hyperactive Ptpn22 −/− T effector cells and maintaining T cell tolerance. The increased T Reg cell functionality could be explained at least in part by increased LFA1 adhesion (see also re...

The role of guanine nucleotides in ras p21 function was determined by using the ability of p21 protein to induce maturation of Xenopus oocytes as a quantitative assay for biological activity. Two oncogenic mutant human N- ras p21 proteins, Asp12 and Val12, actively induced maturation, whereas normal Gly12 p21 was relat...

Rationale: Atheroprogression is a consequence of nonresolved inflammation, and currently a comprehensive overview of the mechanisms preventing resolution is missing. However, in acute inflammation, resolution is known to be orchestrated by a switch from inflammatory to resolving lipid mediators. Therefore, we hypothesi...

Increasing evidence indicates that endoplasmic reticulum (ER) stress activates the adaptive unfolded protein response (UPR), but that beyond a certain degree of ER damage, this response triggers apoptotic pathways. The general mechanisms of the UPR and its apoptotic pathways are well characterized. However, the metabol...

Mitochondrial ability of shaping Ca 2+ signals has been demonstrated in a large number of cell types, but it is still debated in heart cells.

Calcium (Ca 2+ ) released from the sarcoplasmic reticulum (SR) is crucial for excitation–contraction (E–C) coupling. Mitochondria, the major source of energy, in the form of ATP, required for cardiac contractility, are closely interconnected with the SR, and Ca 2+ is essential for optimal function of these organelles. ...

Abstract Clinical outcomes of gastrointestinal stromal tumor (GIST)–bearing patients treated with imatinib mesylate (IM) are variable.

This paper demonstrates that the presence of NK cells in patients with gastrointestinal stromal tumour treated with imatinib serves as an independent prognostic factor of clinical response, suggesting that off-target effects of imatinib that stimulate NK cells may partially account for its therapeutic success.

Autophagy is a cell biological pathway affecting immune responses. In vitro, autophagy acts as a cell-autonomous defense against Mycobacterium tuberculosis , but its role in vivo is unknown. Here we show that autophagy plays a dual role against tuberculosis: antibacterial and anti-inflammatory. M . tuberculosis infecti...

Axing Autophagy When intracellular pathogens like Legionella pneumophila take up residence in mammalian host cells, they must combat the efforts of the host cell to attack them. Autophagy is a process by which cells digest their own constituents, often involved in response to starvation or pathogen attack. Choy et al. ...

This is an elegant recent example of how bacteria defend themselves against autophagy by preventing LC3 lipidation, which thus stalls the autophagic response.

Trapoxin is a microbially derived cyclotetrapeptide that inhibits histone deacetylation in vivo and causes mammalian cells to arrest in the cell cycle. A trapoxin affinity matrix was used to isolate two nuclear proteins that copurified with histone deacetylase activity. Both proteins were identified by peptide microseq...

Antibodies specific for the insulin-regulatable glucose transporter (GLUT 4) were used to immunolocalize this protein in brown adipose tissue from basal- and insulin-treated rats.

ABSTRACT The insulin-responsive glucose transporter GLUT4 plays an essential role in glucose homeostasis. A novel assay was used to study GLUT4 trafficking in 3T3-L1 fibroblasts/preadipocytes and adipocytes. Whereas insulin stimulated GLUT4 translocation to the plasma membrane in both cell types, in nonstimulated fibro...

The authors show that adipocytes contain a recycling pool of GLUT4 and a pool of GLUT4 that is sequestered in GSVs, which are mobilized to the plasma membrane only after stimulation with insulin.

The translocation of a unique facilitative glucose transporter isoform (GLUT4) from an intracellular site to the plasma membrane accounts for the large insulin-dependent increase in glucose transport observed in muscle and adipose tissue.

Insulin stimulates translocation of GLUT4 storage vesicles (GSVs) to the surface of adipocytes, but precisely where insulin acts is controversial. Here we quantify the size, dynamics, and frequency of single vesicle exocytosis in 3T3-L1 adipocytes. We use a new GSV reporter, VAMP2-pHluorin, and bypass insulin signaling...
10.1038/nrm3351
The authors use a novel TIRFM approach to distinguish vesicles by size and show that immediately after insulin stimulation GLUT4 is mainly exocytosed from GSVs, but after prolonged insulin treatment GLUT4 arrives at the plasma membrane in endosomes.

The intracellularly stored GLUT4 glucose transporter is rapidly translocated to the cell surface upon insulin stimulation. Regulation of GLUT4 distribution is key for the maintenance of whole body glucose homeostasis. We find that GLUT4 is excluded from the plasma membrane of adipocytes by a dynamic retention/retrieval...

Recently, we described a 160 kDa protein (designated AS160, for Akt substrate of 160 kDa) with a predicted Rab GAP (GTPase-activating protein) domain that is phosphorylated on multiple sites by the protein kinase Akt.
