A Simple Way to Produce Gold Nanoshells for Cancer Therapy
Gold nanoshells (GNSs), formed by a silica core surrounded by a gold shell, present a shift on their surface plasmon resonance (SPR) to the near-infrared (NIR) part of the electromagnetic spectrum when synthesized with specific dimensions. This chapter presents a simple method to prepare the nanoshells, a step-by-step characterization, as well as their absorbance spectrum. For the synthesis, silica spheres, with approximately 190 ± 5 nm in diameter, were prepared using the Stöber method and then functionalized with 3-aminopropyltriethoxysilane (APTES). The gold nanoparticles (GNPs), with a diameter of 7 ± 3 nm, were produced by the reduction of chloroauric ...
Regulation of immune system cell functions by protein kinase C
Members of the protein kinase C (PKC) family of Ser/Thr kinases are encoded by nine distinct but closely related genes, which give rise to more than 12 different protein isoforms via a mechanism of alternative RNA splicing. Most PKC proteins are ubiquitously expressed and participate in a plethora of functions in most cell types. A majority of PKC isoforms is also expressed in cells of the immune system in which they are involved in signal transduction downstream of a range of surface receptors, including the antigen receptors on T and B lymphocytes. PKC proteins are central to signal initiation and propagation, and to the regulation of processes leading to immune cell proliferation, differe...
Advances in TNF Family Research
The biennial TNF-family conferences have been held over the past 20 years, from the time that TNF was cloned. These meetings have followed the enormous progress in this field. Much is now known about the members of the TNF ligand and receptor families, their signaling proteins, mechanisms of action and cellular functions. This volume is the proceedings of the 12th TNF International Conference, held in April 2009. This conference focuses on the physiological, pathophysiological, and medical significance of these important regulators. Sessions at the meeting specifically address their involvement in immunity, development, apoptosis, autoimmunity, cancer, and infection, the normal function and pathology of the neuronal system, as well as major unresolved questions about their mechanisms of action.
Nanotechnology in Cancer Treatment
The collection is diverse in the topics covered as well as the contributors, who come from across the globe. The overall topic is inherently a complex one since it integrates the exceptional complexity of cancer biology and treatment with the large and rapidly growing number of potential nanostructures and modifications that could be applied to treatment. In both cancer and nanotechnology, a very small change of a relevant variable can generate exceptional variability in biological outcome, creating inherent challenges to clinical adoption. As with many high-potential fields in medicine, the recognition of exceptional potential for nanotechnology in cancer therapy, with associated expectatio...
Connecting the Dots Between Inflammation and the Inner Workings of Programmed Cell Death
Programmed cell death (PCD) is central in maintaining the life of multicellular organisms, during development as well as in healthy adulthood or in the context of disease. The best understood form of PCD is apoptosis, a caspase mediated, immunologically silent cell death that can be initiated in probably all cell types upon aging, lack of growth support, critical damage or infection. One of the key pathways of apoptosis involves mitochondrial outer membrane permeabilization (MOMP), a process tightly regulated by members of the BCL-2 family. Whereas PCD and apoptosis were used synonymously in the past, other forms of PCD have been discovered more recently, including RIPK1/3- and MLKL-dependen...
AACR 2022 Proceedings: Part B April 11-13
The AACR Annual Meeting is the focal point of the cancer research community, where scientists, clinicians, other health care professionals, survivors, patients, and advocates gather to share the latest advances in cancer science and medicine. From population science and prevention; to cancer biology, translational, and clinical studies; to survivorship and advocacy; the AACR Annual Meeting highlights the work of the best minds in cancer research from institutions all over the world.
