Immunogenetics

Immunogenetics:

Immunogenetics is the study of the genetic basis of the immune response. It combines aspects of immunology and genetics to understand how genetic variations affect the immune system's functioning and its response to pathogens.

Here are some key points about immunogenetics:

1. Major Histocompatibility Complex (MHC): MHC genes play a crucial role in the immune system by presenting peptide fragments to T cells, which then initiate an immune response. Variability in MHC genes influences individual susceptibility to infectious diseases, autoimmune diseases, and transplant rejection. 

2. Autoimmune Diseases: Genetic predispositions can lead to autoimmune diseases, where the immune system mistakenly attacks the body's own tissues. Studies in immunogenetics help identify specific genes and genetic mutations associated with these conditions.

3. Allergies and Asthma: Genetic factors contribute to the development of allergic reactions and asthma. Research in this field aims to understand the genetic mechanisms underlying these conditions to improve diagnosis and treatment.

4. Infectious Diseases: Host genetic factors can influence susceptibility to infectious diseases. Immunogenetics studies help identify genetic variants that affect how individuals respond to infections, which can guide the development of personalized medicine approaches.

5. Cancer Immunotherapy: Understanding the genetic makeup of both the tumor and the patient’s immune system can improve the effectiveness of immunotherapies. Genetic profiling can help predict which patients are likely to respond to specific treatments.

6. Transplantation: Genetic matching of donor and recipient MHC (also known as HLA in humans) is crucial for the success of organ and tissue transplants. Immunogenetics research helps improve matching techniques and reduces the risk of transplant rejection.

7. Vaccines: Genetic factors can influence individual responses to vaccines. Research in immunogenetics aims to develop more effective vaccines and personalized vaccination strategies based on genetic profiles.

Genetic factors with clinical trial stoppage

Genetic factors associated with reasons for clinical trial stoppage Many drug discovery projects are started but few progress fully through clinical trials to approval. Previous work has shown that human genetics support for the therapeutic hypothesis increases the chance of trial progression. Here, we applied natural language processing to classify the free-text reasons for 28,561 clinical trials that stopped before their endpoints were met. We then evaluated these classes in light of the underlying evidence for the therapeutic hypothesis and target properties. We found that trials are more likely to stop because of a lack of efficacy in the absence of strong genetic evidence from human populations or genetically modified animal models. Furthermore, certain trials are more likely to stop for safety reasons if the drug target gene is highly constrained in human populations and if the gene is broadly expressed across tissues. These results support the growing use of human genetics to ...

Post-Stroke Cardiovascular risks

Study finds genetic factors key to post-stroke cardiovascular risks In a recent study published in the journal Stroke , researchers identify genetic and molecular risk factors for subsequent cardiovascular outcomes after incident stroke in an effort to identify potential therapeutic targets to improve patient prognoses. Identifying the causes of stroke Stroke is a major global health issue that causes significant disability and mortality, particularly arterial ischemic stroke (AIS). AIS, which is a type of stroke caused by blocked blood flow to the brain, is responsible for up to 85% of stroke cases. AIS arises due to cerebral blood vessel blockage, with modifiable risk factors including hypertension, diabetes, dyslipidemia, atrial fibrillation, obesity, and lifestyle behaviors. Although genome-wide association studies (GWAS) often focus on incident strokes, studying subsequent events can provide new insights into stroke progression. Further research is crucial to identify genetic and...

Type of Inherited Blindness in Dogs

Genetic test could eradicate a type of inherited blindness in dogs A mountain rescue dog whose duties ended after her eyesight failed has helped scientists create a test that could eradicate the genetic eye condition in her breed for good. Shola the English shepherd has an inherited eye disease called progressive retinal atrophy (PRA) that causes the light-sensitive cells at the back of the eye to deteriorate, eventually leading to blindness. PRA affects more than 100 dog breeds, can be caused by a number of different genetic variants and has no treatment. For some types, symptoms do not appear until the dog is several years old , by which point they may have passed their genes on to puppies. Katherine Stanbury, the first author of the research from the University of Cambridge, said Shola was four years old when she began struggling with her vision in dim light. “She was sent to a veterinary ophthalmologist and they confirmed that she had PRA,” said Stanbury. “And then it turned out h...
