Angiogenesis is the physiological process where new blood vessels grow from existing ones, in order to replenish tissues suffering from inadequate blood supply. Perhaps the most studied angiogenic process occurs in solid tumors whose growing mass and expanding cells create a constant demand for additional supply of oxygen and nutrients for survival. However, other physiological and clinical conditions, such as wound healing, ischemic events, autoimmune and age-related diseases also involve angiogenesis. Angiogenesis is a well-structured process that begins when oxygen and nutrients are depleted, leading to the release of chemokines and growth factors that attract immune cells, particularly m...
Clearance of apoptotic cells is essential for proper development, homeostasis and termination of immune responses in multicellular organisms. Thus, cellular and molecular players taking part in the sequential events of this process are of great interest. Research in the last 20 years has indicated that specific ligands and receptors take part in the attraction of immune cells toward apoptotic targets and in the interactions between apoptotic cells and professional as well as non-professional phagocytes that engulf them. Moreover, phagocytosis of apoptotic cells (efferocytosis) leads to significant phenotypic changes in the engulfing cells suggesting that it is a major fate-determining event ...

Glioblastoma multiforme (GBM) is a uniformly fatal primary brain tumour. Whilst many therapeutic interventions have been studied pre-clinically very few new therapies have been approved for the use of GBM therapy. These tumours present a unique challenge due to their location within the brain, making delivery of therapeutic interventions challenging. Active immunotherapy represents an attractive avenue for therapy, with activated immune cells being shown to cross the blood brain barrier and penetrate brain tumours. Despite several advances being made in numerous other cancer types, many immunotherapeutic interventions in GBM have failed to make it past phase 3 clinical trials and as of now (2022) no immunotherapeutic interventions have been approved for the therapy of GBM.
The newest volume in the Elections in Israel series focuses on the twentieth Knesset elections held in March 2015 following the collapse of the third Netanyahu government. Prime Minister Benjamin Netanyahu’s main opposition party, the Zionist Camp, ran a negative personalized election campaign, assuming that Israelis had grown tired of him. Netanyahu, however, achieved a surprising and dramatic victory by enhancing and radicalizing the same identity politics strategies that helped him win in 1996. The Elections in Israel 2015 dissects these and other campaigns, from the perspective of the voters, the media and opinion polls, the political parties, and electoral competition. Several contrib...
