International Journal of Immunology is a peer-reviewed open access journal that publishes original research articles as well as review articles in all areas of immunology. Immunology is a diverse and growing discipline that can be defined as the study of the tissues, cells and molecules involved in host defense mechanisms. Immunologists attempt to understand how the immune system develops, how the body defends itself against disease, and what happens when it all goes wrong. Priority is given to work that provides fundamental insight into the workings of the immune system. Areas covered include, but are not limited to, innate immunity and inflammation; development; immune receptors, signaling and apoptosis; antigen presentation; gene regulation and recombination; cellular and systemic immunity; vaccines; immune tolerance; autoimmunity and tumor immunology, microbial immunopathology; and transplantation.
The great advances in immunology in recent years make this field one of the most dynamic and rapidly growing in biological sciences. This remarkable growth is stimulated by the influx of investigators from other disciplines such as biochemistry, genetics, molecular biology, microbiology, virology and various medical disciplines. These disciplines are so well interlinked with immunology that no immunological challenge can now be properly addressed without sophisticated applications of expertise of combinations of these disciplines. As a consequence, immunology has become a vast and rich field encompassing discoveries and outlooks that range from the highly clinical to the highly molecular. Although such perspectives may appear diverse, they are, in fact, extremely interdependent. The journal seeks to present a balanced overview of contemporary immunology and melds together different aspects of molecular immunology, immunobiology and clinical immunology.
Immunology is the branch of biomedical science that deals with the response of an organism to antigenic challenge and its recognition of what is self and what is not. It deals with the defense mechanisms including all physical, chemical and biological properties of the organism that help it to combat its susceptibility to foreign organisms, material, etc
Immunology has its origins in the study of how the body protects itself against infectious diseases caused by microorganisms, such as bacteria, viruses, protozoa, and fungi, and also parasitic organisms, such as helminth worms. Research / review articles deals with, among other things, the physiological functioning of the immune system in states of both health and disease; malfunctions of the immune system in immunological disorders (autoimmune diseases, hypersensitivities, immune deficiency, transplant rejection); the physical, chemical and physiological characteristics of the components of the immune system in vitro, in situ, and in vivo are of prime interest.
We take great pleasure in welcoming you to our new journal, International Journal of Immunology. We have created this publication with the intention of providing a space for the generation of knowledge, dialogue, critique, debate, and collaboration among an international community of immunologists, pathologists, researchers, scholars, etc.
Our vision is to create a high-quality publication that will be relevant, challenging, thought-provoking, for graduate students, academic researchers and scholars. We welcome original research papers, reviews articles, case studies, book reviews, and works-in progress.
We look forward to welcoming your submissions.

Immunology Leadership & Committees consider proposals for Special Issues Editors will return a decision on your proposal within Two weeks of receipt. To enrich our vision of making the scientific information available at an ease of access, Immunology Leadership & Committees initiated special issue for the open access journals. All the articles published under a special issue focuses on a single topic providing the complete information about the ongoing research providing more insight on an emphasized topic of research enabling the readers access wide forecasted information on a particular topic Issue.
Special Issue Proposals: Special Issue deals with focused research topics of high interest, falling under the scope of the Journal. Special Issues are the pool of articles under a current topic selected from the Ongoing Research under specific discipline. The aim of the Special Issue is to provide a platform for the researchers to understand the recent advancements and challenges in particular areas of research. These articles will provide an opportunity to the readers to understand and access the scientific information.
We encourage potential scientists to organize the Special Issue in their field of interests that fits within the Journal scope.

Noah Isakov is the Joseph H. Krupp Professor in Cancer Immunobiology at the Shraga Segal Department of Microbiology, Immunology and Genetics, the Goldman Medical School, Ben Gurion University of the Negev, in Beer Sheva, Israel. His major interest is in signal transduction mechanisms in normal and transformed cells, predominantly in the immune system. He was involved in the discovery and characterization of new signaling molecules in T lymphocytes and continues studying the intricate signaling pathways that regulate T lymphocyte functions and T lymphocyte-mediated immune responses.

M. Sc. 1974-1976, Immunology, Department of Cell Biology, The Weizmann Institute of Science, Rehovot, Israel. Thesis: "The role of Ia antigens in genetic regulation of immune responses".

Our main research interest focuses on T-cell antigen receptor (TCR)-directed signal transduction pathways in T lymphocytes, as well as a comparative analysis of signal transduction mechanisms in normal versus transformed cells. We aim at identifying and characterizing the mechanism of action of several important effector molecules in T lymphocytes and study their role in the immunological synapse. Among the proteins that we study are protein kinase C theta (PKCθ), ZAP-70, Crk and PICOT. PKCθ and ZAP-70 are essential for the regulation of T lymphocyte activation and differentiation, are key molecules in the immunological synapse of TCR triggered T cells, and their absence leads to immune deficiencies. The Crk adaptor proteins are involved in the regulation of signaling mechanisms downstream of the TCR, while PICOT, which associates with PKCθ in T lymphocytes and was found to be essential for embryonic developmentis highly expressed in several types of malignancies, including human leukemia, although its exact biological role is still enigmatic.
