Immune support cancer fighting

Timothy W Jolis, Brenna M Brucker, Christoph Schorl, James N Butera, Peter J Quesenberry
Microchimerism has generally been shown to protect against cancer (Gilmore et al. in Exp Hematol 36(9):1073-1077, 2008). The mechanism of how this occurs is an area of intense study, as it may lead to new cancer treatments. The leading theory is that microchimeric cells perform immune surveillance by directly fighting cancerous cells and that they also act as stem cells, repairing damaged tissue (Khosrotehrani et al. in JAMA 292:75-80, 2004). However, there is conflicting evidence to support this theory. Several small studies have found few microchimeric cells in tumor tissue (Gadi in Breast Cancer Res Treat 121(1):241-244, 2010; Cirello et al...

Although most researches and therapies have been focused on the tumor itself, it is becoming clear that immune cells can not only suppress tumor development but support and maintain their malignant type. Promising recent developments in immunology will provide opportunities for tumor-specific immunotherapy, which can orchestrate the patients immune system to target, fight and eradicate cancer cells without destroying healthy cells. However, antitumor immunity driven by self-immune system alone may be therapeutically insufficient...

Tumor-associated antigens have emerged as important immunotherapeutic targets in the fight against cancer. Germline tumor antigens, such as WT1, Wilms' tumor gene 1, are overexpressed in many human malignancies but have low expression in somatic tissues. Recent vaccination approaches to target WT1 have been hampered by poor in vivo immune potency, likely due to the conserved self-antigen nature of WT1. In this study, we use a novel synthetic micro-consensus SynCon DNA vaccine approach with the goal of breaking tolerance and increasing vaccine immune potency...

The significant role of the immune system in cancer treatment has given rise to an emerging field of study within oncology, and one that is attracting increasing attention from researchers. Immunotherapy has demonstrated that the immune system is crucial in the fight against cancer. This challenge has led researchers to analyze whether the immune influencing capacity of immunonutrition may aid in improving immune status, modulate the acquired immune response, decrease the treatment toxicity and improve patient outcomes...

BACKGROUND: Correct function of the immune system depends on close cooperation between stimulation and inhibition signals, which protect an organism from outside microorganisms and other agents, but also protects healthy tissues against possible self-destructing attacks of the immune system. However, the inhibitory mechanisms can be abused by cancer cells that evade immune responses and, in fact, they help develop cancer. Therefore, one of the characteristics of cancer cells is the ability to evade immune recognition...

The frequency of Candida infections is currently rising, and thus adversely impacting global health. The situation is exacerbated by azole resistance developed by fungal pathogens. Candida tropicalis is an opportunistic pathogen that causes candidiasis, for example, in immune-compromised individuals, cancer patients, and those who undergo organ transplantation. It is a member of the non-albicans group of Candida that are known to be azole-resistant, and is frequently seen in individuals being treated for cancers, HIV-infection, and those who underwent bone marrow transplantation...

Immunotherapy dates back to 1868 when German physicist Busch intentionally infected patients suffering from soft tissue sarcoma with erysipelas. Rapid tumor shrinkage was observed but response was only partial and tumor recurrence subsequently occurred. It was William B. Coley who in 1891 injected a patient with a soft tissue sarcoma with streptococcal cultures. Following a severe attack of erysipelas, the tumor underwent extensive necrosis and the patient remained diseasefree for eight years. The mixture of Streptococcus and other bacteria including Seratia marcescens, Staphylococcus and Escherichia coli was referred to as Coleys toxin and was used for the next 45 years...

Adoptive cell immunotherapy is a novel tool in the fight against cancer. Serving both effector and memory functions for the immune system, T cells make an obvious candidate for adoptive cell immunotherapy. By modifying native T cells with a chimeric antigen receptor (CAR), these cells can theoretically be targeted against any extracellular antigen. To date, the best-studied and clinically validated CAR T cells recognize CD19, a cell surface molecule on B cells and B cell malignancies. These CD19-directed T cells have shown clinical utility in chronic lymphocytic leukemia, acute lymphoblastic leukemia (ALL), and non-Hodgkin's lymphomas, with some patients achieving long-term disease remissions after treatment...

BACKGROUND: The tumor microenvironment plays a determinative role in stimulating tumor progression and metastasis. Notably, tumor-stroma signals affect the pattern of infiltrated immune cells and the profile of tumor-released cytokines. Among the known molecules that are engaged in stimulating the metastatic spread of tumor cells is the S100A4 protein. S100A4 is known as an inducer of inflammatory processes and has been shown to attract T-cells to the primary tumor and to the pre-metastatic niche...

Inflammation regulates energy metabolism in both physiological and pathological conditions. Pro-inflammatory cytokines involves in energy regulation in several conditions, such as obesity, aging (calorie restriction), sports (exercise), and cancer (cachexia). Here, we introduce a view of integrative physiology to understand pro-inflammatory cytokines in the control of energy expenditure. In obesity, chronic inflammation is derived from energy surplus that induces adipose tissue expansion and adipose tissue hypoxia...

Macrophages are tissue-resident immune cells that play a critical role in maintaining homeostasis and fighting infection. In addition, these cells are involved in the progression of many pathologies including cancer and atherosclerosis. In response to a variety of microenvironmental stimuli, macrophages can be polarized to achieve a spectrum of functional phenotypes. This review will discuss some emerging evidence in support of macrophage phenotypic regulation by physical and mechanical cues. As alterations in the physical microenvironment often underlie pathophysiological states, an understanding of their effects on macrophage phenotype and function may help provide mechanistic insights into disease pathogenesis...

INTRODUCTION: Cancer, the major killer disease of the century requires a multi-pronged approach and among the latest modalities of treatments, Immunotherapy occupies a promising role. Immunotherapy for cancer was first started to be practised in the NIH and cell based immunotherapy for cancer is in practice for the past three decades. ([1, 2]) There are several literatures from various countries on the successful application of cell based Immunotherapies for various solid tumours and haematological malignancies...

Inflammatory cells are involved in tumour initiation and progression. In parallel, the adaptive immune response plays a key role in fighting tumour growth and dissemination. The double-edged role of the immune system in solid tumours is well represented in colorectal cancer (CRC). The development and progression of CRC are affected by the interactions between the tumour and the host's response, occurring in a milieu named tumour microenvironment. The role of immune cells in human CRC is being unravelled and there is a strong interest in understanding their dynamics as to tumour promotion, immunosurveillance and immunoevasion...

It is thought that the development of vaccines for the treatment of infectious diseases and cancer is likely to be achieved in the coming decades. This is partially due to a better understanding of the regulatory networks connecting innate with adaptive immune responses. The innate immune response is triggered by the recognition of conserved pathogen-associated molecular patterns by germ line-coded pattern recognition receptors. Several families of pattern recognition receptors have been characterized, including Toll-like receptors and nucleotide-binding domain receptors...

Cytotoxic T-lymphocyte associated antigen 4 (CTLA-4) plays a key role in restraining the adaptive immune response of T-cells towards a variety of antigens including tumor associated antigens (TAAs). The blockade of this immune checkpoint elicits an effective anticancer immune response in a range of preclinical models, suggesting that naturally occurring (or therapeutically induced) TAA specific lymphocytes need to be "unleashed" in order to properly fight against malignant cells. Therefore, investigators have tested this therapeutic hypothesis also in humans: the favorable results obtained with this strategy in patients with advanced cutaneous melanoma are revolutionizing the management of this highly aggressive disease and are fueling new enthusiasm on cancer immunotherapy in general...

In recent years, huge investigations on cancer progression and invasion have led to under-stand the pivotal role of tumor microenvironment. The current era of cancer therapy is based on the concept of simply targeting precise mechanisms to kill or to suppress the growth and expansion of malignant cells. Clinical data clearly correlate with in-vitro re-sults, emphasizing the direct impact of cancer environment on disease progression. This provides the opportunity to advance cancer therapy by virtue of targeting cancerous cells and non-cancerous component of tumor in a combinatorial manner...

BACKGROUND: Despite progress in conventional cancer therapies, cancer is still one of the leading causes of death in industrial nations. Therefore, an urgent need of progress in fighting cancer remains. A promising alternative to conventional methods is immune therapy. This relies on the fact that low-immunogenic tumours can be eradicated if an immune response against them is induced. Peptide vaccination is carried out by injecting tumour peptides into a patient to trigger a specific immune response against the tumour in its entirety...

Major breakthroughs have been realized in controlling cancer in the past five decades. However, for patients in low- and middle-income countries (LMICs), many of these advances are nothing but an aspiration and hope for the future. Indeed, the greatest challenge we face in oncology today is how to reconcile small, incremental and significant improvements in the management of cancer with the exponentially increasing costs of new treatments. Emerging economies are attempting to address this important issue of access to cancer medications...
