Immune tolerance refers to a state where our immune system learns to recognize our body's own cells as normal and does not attack them. It helps in preventing our immune system from mistakenly attacking healthy cells as if they were harmful.

Some people, for example, undergo an intensive treatment
called immune tolerance induction therapy, which involves regular intravenous administration of coagulation factors.
The ITN develops and conducts clinical studies of
immune tolerance therapies — highly targeted treatments designed to prevent disease - causing immune responses, without compromising the natural protective properties of the immune system.
Better understanding of
how immune tolerance is lost and regained could inform efforts toward establishing stronger and more durable phases of remission in autoimmune disease and toward preventing cancer recurrence.
The latest study builds off of work Kawai and his colleagues began fourteen years ago, when they launched the first clinical trial that attempted to use bone marrow to induce
immune tolerance for kidney recipients, to avoid the sometimes dangerous side effects of life - long immosuppressive therapy.
Made major contributions to the field of immunology through his studies
on immune tolerance in animal models, with particular focus on transplantation tolerance and autoimmunity, in addition to pioneering the use of therapeutic monoclonal antibodies against T cells, resulting in the development of Campath - 1H, the first humanised monoclonal antibody to be used therapeutically.
By contrast, the neoantigen vaccine is custom - made for each patient using antigens produced by mutations unique to the patient's cancer and only present on cancer cells, thus bypassing the nature
immune tolerance process.
Main interest of the Unit is to unravel the key molecular and cellular mechanisms
controlling immune tolerance, responsible for maintaining tissue homeostasis and avoiding adverse immune responses.
In the new study, scientists built upon previous discoveries that a safe, non-reproducing vaccine strain of T. gondii could cure mice of several types of solid tumors, and identified which parasite proteins and which immunological pathways are required to
break immune tolerance.
Although immune tolerance can occur — in rare cases, transplant recipients who stop taking immunosuppressants have not rejected their foreign organs — researchers don't have a clear picture of what is happening at the molecular and cellular levels to allow this to happen.
If researchers can complete their 50 - year quest to induce
immune tolerance safely and selectively, the prospects for hundreds of thousands of transplant recipients would be greatly improved, and so, too, might the prospects for controlling autoimmune diseases.
Although the ideal remains a gene therapy that both corrects the disease and
offers immune tolerance, some scientists have focused on treating inhibitor formation, without worrying about fixing the disease.
When the tumor - fighting T cells are kept in check by inhibitory regulatory T cells, scientists speak of «
peripheral immune tolerance.»
The Unit aims at studying and modulating antigen (Ag)- specific immune responses, to develop efficient therapeutic approaches to (re) establish Ag -
specific immune tolerance in allogeneic bone marrow and solid organ transplantation, autoimmune diseases, allergy, and gene therapy.
The mission of the ITN is the development of
new immune tolerance therapies — highly specific treatments that reprogram the immune system to inhibit disease - causing immune responses while keeping beneficial, disease - fighting immune responses intact.
Microchimerism is the presence of small populations of genetically disparate cells within a host as a result of transfusion or transplacental trafficking during pregnancy, and may
influence immune tolerance in the recipient.
IDO1 is one of the enzymes responsible for catabolizing tryptophan in a pathway essential for
maternal immune tolerance toward the conceptus (37, 38).
If you notice the development of indentations (almost like small «holes») on this area, it may indicate a
weaker immune tolerance in the lungs and higher susceptibility to infection including colds and respiratory issues.
By learning how to
overcome immune tolerance and immunosuppression caused by the tumor, this study and other research UC Davis is conducting on immunotherapy hopes to provide oncologists more options for treating cancer in both pets and their owners.
At least in theory, producing regulatory T cells could
promote immune tolerance and prevent the body from rejecting newly - transplanted cells.
In the skin, for example, Rosenblum and colleagues have previously shown that Tregs help
establish immune tolerance to healthy skin microbes in newborn mice, and these cells also secrete molecules that help with wound healing into adulthood.
The study authors say that is because these vaccines have generally been made with tumor antigens that are too similar to antigens on normal cells: as a result, the body generates a weaker immune response to avoid harming normal cells, a process
called immune tolerance.
Dr. Bluestone has spent over 35 years working as an immunologist interested in
immune tolerance as it relates to autoimmunity and organ transplantation.
Despite the increasing incidence and severity of food allergies, the details on
how immune tolerance to dietary antigens is normally established remain largely unknown.
The IDO pathway is immunosuppressive and was originally described as one of the mechanisms for maternal —
fetal immune tolerance.
Saturday, May 5, 6:00 PM, Ballroom D Jeffrey A. Bluestone Univ. of California, San Francisco Treg -
mediated immune tolerance in health and disease
In the first mouse model of the progressive form of multiple sclerosis, nanoparticles that
created immune tolerance to myelin prevented the development of progressive MS.
University of California - San Francisco Translating AIRE - control
of immune tolerance to human autoimmunity
Brutally disappointed, she overhauled her career, returned to basic research, and now works at Stanford University in Palo Alto, California, where she studies stem cell transplants and
immune tolerance.
When the body has an imbalanced number of Treg cells,
its immune tolerance can fail and experience autoimmune disorders such as arthritis.
Different classes of MHC molecules exist and are involved in immunity against pathogens and tumor cells as well as the formation of
immune tolerance to self - antigens.
One gene that controls this pathway, HDAC7, is known to be a key factor in
immune tolerance and the new data strongly suggests exploring the possibility that drugs affecting HDAC7 function may serve as future therapeutics in PSC.
The aim of the Pre-POINTearly study is therefore to build up
immune tolerance to insulin and thus block the autoimmune process.»
To identify the explanation for this observation, the team grafted a heart into the abdominal cavity of experimental mice and induced
immune tolerance.
Using a mouse model of cardiac transplantation, they found that
immune tolerance can spontaneously recover after an infection - triggered rejection event, and that hosts can accept subsequent transplants as soon as a week after.
While difficult to achieve,
immune tolerance — in which a transplanted organ is accepted without long - term immunosuppression — can be induced in some patients.
