In animal models, this first mRNA-LNP C.
Tests, in mice, of a drug developed by the researchers showed that regulatory T cells can be attracted to specific body parts, boosted in number, and activated to suppress immuneresponse and rebuild tissue.
Researchers have discovered a protein variant that serves as a knob for regulating the body's innate immuneresponse. The findings could lead to new therapies for Long COVID, autoimmune disorders, and more.
Researchers report that all nine patients in a clinical trial being treated for stage III or IV clear cell renal cell carcinoma (a form of kidney cancer), generated a successful anti-cancer immuneresponse after initiation of a personalized cancer vaccine.
A strain of the bacterium harbored in the children's gut microbial communities possessed a previously unknown gene capable of producing and metabolizing key molecules involved in regulating many important functions ranging from appetite, immuneresponses, neuronal function, and the ability of pathogenic bacteria to produce disease.
By adding synergistic self-adjuvanting properties to Covid-19 RNA vaccines, researchers showed they could significantly boost the immuneresponse generated in mice.
Immunotherapies, which mobilize the body's immune defenses against a cancer, have not been effective for GBM, in part because the tumor's surrounding environment is largely impenetrable to assaults from the body's immune system.
Now, an article challenges this hypothesis by showing that mice with high infectious exposures from birth have the same, if not an even greater ability to develop allergic immuneresponses than 'clean' laboratory mice.
Researchers have demonstrated that a transplant surgical procedure (called 'needle trauma') triggers a profound immuneresponse and causes the death of most grafted dopamine neurons.
The finding upends 40 years of conventional wisdom and may offer new insights into cancer, viral infections and immuneresponses. They hijack a little-known piece of the cell's DNA repair function to close themselves into a ring-like shape and then create a matching double strand.
The most comprehensive map of the developing human thymus sheds light on how immuneresponses are built and maintained at early life, with implications for understanding and treating immunodeficiency, autoimmunity, and cancer.
The first peer-reviewed study in North America examining the timing between the first and second doses of COVID-19 mRNA vaccines shows that a longer dose interval leads to a stronger immuneresponse. The study is funded by the Government of Canada through its COVID-19 Immunity Task Force (CITF).
Individualised cancer vaccines are tailored to each patient’s tumour, helping the immune system mount cancer-specific immuneresponses that can boost checkpoint inhibitor efficacy. Espen integrates clinical and research expertise as Director of Medical Affairs.
Some hereditary genetic defects cause an exaggerated immuneresponse that can be fatal. Using the CRISPR-Cas9 gene-editing tool, such defects can be corrected, thus normalizing the immuneresponse, as researchers led by Klaus Rajewsky from the Max Delbrück Center now report in “Science Immunology.”
Loxo Oncology at Lilly, a research and development group of Eli Lilly and Company (NYSE: LLY), and Kumquat Biosciences today announced an exclusive collaboration focused on the discovery, development and commercialization of potential novel small molecules that stimulate tumor-specific immuneresponses.
By examining the genomes of bacteria collected from hundreds of people with persistent Salmonella infections, they discovered genetic mutations that both reduce the bacteria’s “virulence,” or ability to infect, and dampen the host’s immuneresponses, creating a kind of molecular camouflage that shields the bacteria from the immune system’s gaze.
Adjuvanted recombinant COVID-19 vaccine candidate triggered strong neutralizing antibody responses in all adult age groups. High immuneresponse after a single dose in patients with prior infection shows strong booster potential. For media and investors only. Issued: London UK. About the Phase 2 study. Sanofi, Empowering Life.
1 Dr Ninh (Irene) La-Beck, from the Department of Immunotherapeutics and Biotechnology at the Texas Tech University Health Sciences Center (TTUHSC) Jerry H. The grant will enable her to investigate the interaction of nanoparticles with the immune system and cancer, supporting the development of new drug delivery systems.
The drugs work by blocking a protein, PD-1 — which helps keep immuneresponses in check — and stimulating the immune system to attack tumors. The researchers soon partnered with Calico Life Sciences , which in collaboration with AbbVie , discovered drug candidates that block the PTPN2 protein.
This interaction inhibits inflammation and immune activation, and in particular prevents macrophages from phagocytosing and destroying cancer cells. By blocking CD24 with an antibody drug, our goal is to powerfully reactivate the anti-cancer immuneresponse and drive therapeutic efficacy.
Reporting in Science , researchers at Massachusetts General Hospital and the Broad Institute of MIT and Harvard have made a surprising discovery about these drugs. They found that mIDH1 inhibitors trick the tumor cells into thinking they are infected with a virus, causing the immune system to mount an antiviral response.
HLA are the critical molecules that our immune systems use to present peptides to T cells and facilitate recognition and killing in immuneresponses to pathogens. HLA-II presents peptides to CD4 T cells thought to be important for indirectly helping immuneresponses and facilitating antibody production.
Their research centres around a remarkable immune protein called IL-31, which not only induces itching but also plays a crucial role in regulating inflammation. In the absence of IL-31, these nerve cells failed to control the immune system, leading to unchecked inflammation.

This is particularly pertinent in immune-based cell therapies like CAR-T, where animals do not mimic the human immuneresponse. Nikki’s life sciences experience spans leadership, commercial and research roles. About the author Nikki Carter Commercial Organoid Innovation Director, Molecular Devices.
Can they deliver healing genes without triggering an overactive immuneresponse? The details are disturbingly reminiscent of the famous case of Jesse Gelsinger , who died from a ferocious immuneresponse to experimental gene therapy in September 1999. An immuneresponse is two-tiered.
More recently, researchers have begun to look at conjugating immunomodulatory agents to antibodies to directly activate an immuneresponse against the tumour. This approach – immune-stimulating antibody conjugates (ISACs) – uses a payload that stimulates the innate and adaptive immuneresponses, recruiting tumour-fighting T cells.
