The main function of the mammalian immune system is to monitor tissue homeostasis, to protect against invading or infectious pathogens and to eliminate damaged cells. Therefore, it is surprising that cancer occurs with such a high frequency in humans. Recent insights that have been gained from clinical studies and experimental mouse models of carcinogenesis expand our understanding of the complex relationship between immune cells and developing tumours. Here, we examine the paradoxical role of… 
Oncogenic stress sensed by the immune system: role of natural killer cell receptors
This Review addresses the current understanding of the mechanisms that detect cellular stresses that are associated with tumorigenesis and that culminate in the recognition and, in some cases, the elimination of the tumour cells by natural killer cells and other lymphocytes that express natural killer cell receptors.
Nod-Like Receptors: Key Molecular Switches in the Conundrum of Cancer
All the current evidence for NLR involvement in the different stages of neoplasia is presented to understand how a single molecular pathway can contribute to conflicting immunological interactions with cancer.
Tumor progression mechanisms: Insights from the central immune regulation of tissue homeostasis
The functional features of the immune system that contribute to the maintenance of normal tissue homeostasis, as well as their disruption in malignant transformations, were analyzed and may provide an insight into cancer evolution in terms of the mechanisms of T-cell competency formation.
Balancing immune response: crosstalk between adaptive and innate immune cells during breast cancer progression
Important new findings revealing the paradoxical role of innate and adaptive leukocytes as regulators of breast carcinogenesis are summarized.
Crosstalk between Innate Lymphoid Cells and Other Immune Cells in the Tumor Microenvironment
Defining the complex network of interactions and crosstalk of ILC with other immune cells and understanding the specific contributions of each type of I LC leading to tumor development will allow the manipulation of their function and will be important to develop new interventions and therapeutic strategies.
Immunosurveillance of cancer cell stress
How distinct situations of cellular stress influence innate and adaptive immunity and the consequent impact on cancer establishment and progression is explored.
Complementing the tumor-specific immunity in tumor radiotherapy.
The role of immune system and inflammation in tumor development has recently rekindled the attention of researchers and Douglas Hanahan and Robert A. Weinberg have listed them to one of the ten
Spontaneous immune responses to sporadic tumors: tumor-promoting, tumor-protective or both?
The role of the dynamic inflammatory tumor microenvironment during cancer development and progression is discussed, and the intriguing question: "Do malignancies develop in spite of-or because of-spontaneous immune responses?" is focused on.
Utilizing Mouse Models of Human Cancer for Assessing Immune Modulation of Cancer Development
relevant literature is reviewed, where mouse models of human cancer development have provided novel insights into mechanisms of pro- versus antitumor immunity.
Impact of the immune system and immunotherapy in colorectal cancer.
The impact of the immune system on the initiation, progression and treatment of cancer, specifically focusing on CRC is discussed.

It is well known that many tumours are potentially immunogenic, as corroborated by the presence of tumour-specific immune responses in vivo. Nonetheless, spontaneous clearance of established tumours
Derangement of immune responses by myeloid suppressor cells
A review examines recent findings on the nature, properties, and mechanisms of action of these myeloid suppressor cells (MSCs) in tumor-bearing mice and cancer patients.

Deficiencies of GM-CSF and Interferon γ Link Inflammation and Cancer
It is reported that aged granulocyte-macrophage colony stimulating factor-deficient mice develop a systemic lupus erythematosis (SLE)-like disorder associated with the impaired phagocytosis of apoptotic cells, demonstrating that the interplay of infectious agents with cytokine-mediated regulation of immune homeostasis is a critical determinant of cancer susceptibility.

Suppression of Lymphoma and Epithelial Malignancies Effected by Interferon γ
Sp spontaneous tumor development in gene-targeted mice lacking interferon (IFN)-γ and/or perforin (pfp), or the immunoregulatory cytokines, interleukin (IL)-12, IL-18, and tumor necrosis factor (TNF) is described.
Natural resistance mechanisms may play a role in protection against chemical carcinogenesis
Experiments indicate that the latent period of primary tumors induced by the injection of methylcholanthrene is also prolonged in these mice, suggesting that NR mechanisms may provide protection against primary chemically induced tumors.
Immune suppression and skin cancer development: regulation by NKT cells
It is shown that natural killer T cells from UV-irradiated donor mice function as suppressor T cells and play a critical role in regulating the growth of UV-induced skin cancers and suppressing adaptive immune responses in vivo.
Regulation of Cutaneous Malignancy by γδ T Cells
In vitro, skin-associated NKG2d+ γδ cells killed skin carcinoma cells by a mechanism that was sensitive to blocking NKG 2d engagement, suggesting that local T cells may use evolutionarily conserved proteins to negatively regulate malignancy.
