Abstract

The adaptive immune response forms an essential part of the cancer immuno-editing process, whereby nascent malignant cells are detected and destroyed prior to forming tumours. The process is tightly controlled to minimise collateral damage to healthy tissue. One of the mechanisms evolved for this purpose and frequently co-opted by malignant cells is the creation of a microenvironment scarce in essential amino-acids through the use of catabolic enzymes such as Indoleamine 2,3-dioxygenase (IDO) , responsible for the rate-limiting step in tryptophan catabolism. The evolutionary conserved GCN2 and mTORC1 pathways respond to amino-acid starvation by triggering emergency homeostatic response programmes that aim to conserve nutrients by shutting down biosynthetic pathways, slowing cell cycle progression and facilitating autophagy. This research project focuses on elucidating the interaction between IDO activity and these pathways and its implications for the immune-editing process. The role of the mTOR kinase as a regulator of T cell fate following exposure to cognate antigen has recently become apparent. Experiments described herein confirm that in murine and human models of T cell activation exposure to tryptophan starvation results in significant mTORC1 inhibition and a modified phenotype with reduced Tbet expression, altered cytokine secretion profile, greatly impaired proliferative capability and expanded CD4+ FoxP3+ CD25high subpopulations. Additional results confirmed that the action of IDO is sufficient to deplete tryptophan from the microenvironment to levels sufficient to depress the mTORC1 axis and trigger GCN2 activity even in tumour cell lines. Lower extracellular tryptophan levels were necessary to perturb these pathways In IDO expressing cell lines, suggesting that compensatory mechanisms allow continued proliferation of malignant cells in the face of conditions that severely impede an anti-cancer immune response. In conclusion, manipulation of the mTORC1 axis via IDO-induced tryptophan depletion is an important tumour immune-escape mechanism that can be a target for cancer immunotherapies.

18. SART: Speeding up Query Processing in Sensor Networks with an Autonomous Range Tree Structure

Abstract

We consider the problem of constructing efficient P2P overlays for sensornets providing "Energy-Level Application and Services". The method presented in \cite{SOPXM09} presents a novel P2P overlay for Energy Level discovery in a sensornet. However, this solution is not dynamic, since requires periodical restructuring. In particular, it is not able to support neither join of sensor\_nodes with energy level out of the ranges supported by the existing p2p overlay nor leave of \emph{empty} overlay\_peers to which no sensor\_nodes are currently associated. On this purpose and based on the efficient P2P method presented in \cite{SPSTMT10}, we design a dynamic P2P overlay for Energy Level discovery in a sensornet, the so-called SART (Sensors' Autonomous Range Tree). The adaptation of the P2P index presented in \cite{SPSTMT10} guarantees the best-known dynamic query performance of the above operation. We experimentally verify this performance, via the D-P2P-Sim simulator (D-P2P-Sim is publicly available at http://code.google.com/p/d-p2p-sim/)., Comment: 11 pages, 23 figures, 5 algorithms or operations
