Summary
Chronic inflammation underlies many diseases. Neuroimmune semaphorins 4A and 4D (Sema4A and Sema4D) regulate inflammation, offering potential for novel immunotherapies targeting these conditions.
Area of Science:
- Immunology
- Neuroscience
- Pathology
Background:
- Chronic inflammation is a key factor in diseases like cardiovascular, pulmonary, autoimmune, neurologic conditions, and cancer.
- Semaphorins 4A and 4D (Sema4A and Sema4D) are newly identified neuroimmune molecules with significant roles in immune regulation.
- Their involvement in fine-tuning inflammatory processes makes them promising targets for therapeutic intervention.
Purpose of the Study:
- To review the current understanding of Semaphorin 4A and 4D (Sema4A and Sema4D) functions.
- To explore their roles in the pathogenesis of chronic inflammatory diseases.
- To highlight their potential as targets for immunotherapy.
Main Methods:
- Literature review of existing research on Sema4A and Sema4D.
- Analysis of studies investigating the link between semaphorins and chronic inflammatory diseases.
- Synthesis of current knowledge on semaphorin-mediated immune regulation.
Main Results:
- Sema4A and Sema4D are expressed in the immune system and play crucial regulatory roles in inflammation.
- These semaphorins are implicated in the development and progression of various chronic inflammatory conditions.
- Evidence suggests their involvement in cardiovascular, pulmonary, autoimmune, neurologic diseases, and cancer.
Conclusions:
- Sema4A and Sema4D are critical regulators of chronic inflammation.
- Targeting Sema4A and Sema4D presents a potential therapeutic strategy for a range of debilitating diseases.
- Further research into semaphorin-based immunotherapies is warranted.

01:28Inflammatory Response
18.1K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

33.9K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

01:22Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
2.8K
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

01:24Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
697
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

01:29Inflammatory Bowel Disease IV: Pharmacological Management
895
Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.
