In this article, Stephan Schann, Chief Scientific Officer at Domain Therapeutics , explains why this class of drug target is so useful despite the challenges they present. Yet although they are a proven drug target family with widespread utility, they remain largely underexplored for tackling inflammatory diseases.
Introduction Therapeutic antibodies have proven to be indispensable medicines for addressing the most debilitating diseases. Agonist antibodies of immune checkpoint regulators These represent a groundbreaking class of immunotherapeutic agents that mimic the natural function of endogenous ligands by binding to specific cell-surface receptors.
By employing a mouse model of Parkinson’s disease, the researchers have illuminated a surprising revelation: it’s the border-associated macrophages (BAMs), not the microglia, that steer the neuroinflammatory response within the brain. However, identifying the precise cells presenting the antigens remained elusive.
G protein-coupled receptors (GPCRs) represent a cornerstone of modern drug discovery due to their crucial role in regulating human physiology and their involvement in numerous diseases. The MC4R-based ConfoGen was used to immunize llamas, resulting in an immuneresponse that generated a highly diverse panel of MC4R-specific agonists.
1 The study reveals a novel bioinformatic approach and tool that holds the potential to empower researchers in designing vaccines capable of inducing a stronger immuneresponse. By selecting specific segments of proteins that elicit robust immune reactions, these vaccines could offer enhanced protection against diseases.
Better activation of innate and adaptive immuneresponses was achieved with CV2CoV, resulting in faster response onset, higher titers of antibodies, and stronger memory B and T cell activation as compared to the first-generation candidate, CVnCoV. “In Induction of innate immunity was investigated via specific cytokine markers.
functions to reset the immune system and potentially provide remission for allergic diseases? 1104 acts upstream in the inflammatory response, targeting one of the first key players: antigen-presenting cells (APCs). In allergic diseases, APCs identify and present unknown antigens to the immune system.
In research published in Scientific Reports , 1 investigators focused on mesenchymal stem cells (MSCs), known for their potential in treating cell defects and regulating immuneresponses. We are studying the placement of organelles within cells and how they communicate to help better treat disease,” said Coskun.
sPLA 2 inhibitors have been developed for the treatment of inflammatory and other conditions such as cardiovascular disease, arteriosclerosis and rheumatoid arthritis. Besides their roles in the degradation of phospholipids, these enzymes also play an important role in the immuneresponse by promoting inflammation.
2 Previously, La-Beck’s research has shown that liposomes made of phospholipids and cholesterol, like those used in patients, doubled tumour size in mice by suppressing their immuneresponse in some tumours. Macrophages were detected as the cells responsible for these negative effects.
This is likely indicative of the heterogeneous nature of the disorder, and it is this complexity and diversity of clinical presentation and effects across multiple organ systems, that has made efforts to identify genetic risk factors using traditional genomic analysis approaches extremely challenging.
A potential game-changer in medicine The implications of this research are vast, potentially transforming the way we treat a variety of diseases involving both the immune and nervous systems. In the absence of IL-31, these nerve cells failed to control the immune system, leading to unchecked inflammation.
These agents simultaneously bind to a tumor-associated protein on cancer cells and the CD3 protein on T-cells, facilitating a targeted anti-cancer immuneresponse. Consequently, these drugs have limited ability to keep patients disease-free and limited impact on patient survival.
Targeting 4-1BB remained of interest to the immuno-oncology field as cell culture experiments and tumor models in mice suggested that robust anti-tumor immuneresponses could be triggered by anti-4-1BB antibody therapies. This is the T cell type most closely associated with anti-tumor immuneresponses.
While the concept of removing mucins from cancer cells seems promising, mucins are present in various forms on all mammalian cells. Their findings, published in Nature Biotechnology, have broad applications as mucins are associated with many diseases, including cystic fibrosis, respiratory diseases, and viruses.
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.
However, mRNA technology is not limited to infectious diseases. This unique mechanism has enabled scientists to rethink how they tackle diseases, paving the way for advancements in oncology, genetic disorders, and regenerative medicine.

The challenge of GPCR drug discovery G protein-coupled receptors (GPCRs) are one of the most desirable and challenging target classes in drug discovery, as their mutation can lead to a wide range of diseases such as cancer, cardiovascular disorders and neurological conditions.
Neoantigen-directed T-cell therapy is a potentially powerful approach that harnesses a patient’s own immune system to fight cancer. One aspect of the collaboration focuses on screening and identification of therapeutic T-cell receptors (TCRs) to target a common shared neoantigen present in many cancer patients.
Also recently, FDA’s Cellular, Tissue, and Gene Therapies Advisory Committe turned down a stem cell treatment for amyotrophic lateral sclerosis, aka ALS, Lou Gehrig’s disease, or motor neuron disease. ALS is a disease of adulthood, beginning typically between 40 and 70 years of age. Most ALS cases are sporadic.
