MHC Full Form In English
MHC is a crucial part of the immune system found in almost all vertebrates. It is a group of genes that helps the body identify and differentiate between its own cells and foreign or harmful substances such as viruses, bacteria, and other pathogens. The proteins produced by MHC genes present small fragments of molecules (called antigens) on the cell surface, allowing immune cells to recognize and respond to infections efficiently.
In simple words, MHC works like an identification card (ID) for cells, helping the immune system decide whether a cell belongs to the body or is an outsider. This makes MHC extremely important in processes like organ transplantation, immune response, and disease resistance.
MHC Full Form In Hindi
MHC हमारे शरीर की प्रतिरक्षा प्रणाली का एक अत्यंत महत्वपूर्ण हिस्सा है। यह जीनों का एक समूह होता है जो हमारे शरीर की कोशिकाओं को एक पहचान प्रदान करता है। इसके माध्यम से प्रतिरक्षा प्रणाली यह तय करती है कि कौन-सी कोशिकाएँ शरीर की अपनी हैं और कौन-सी बाहरी या हानिकारक हैं।
जब कोई वायरस, बैक्टीरिया या अन्य रोगजनक शरीर में प्रवेश करता है, तो MHC प्रोटीन इन रोगजनकों के छोटे-छोटे अंश (एंटीजेन) को पकड़कर कोशिका की सतह पर प्रदर्शित करते हैं। इसके बाद प्रतिरक्षा कोशिकाएँ इन संकेतों को पहचानकर तुरंत प्रतिक्रिया देती हैं और संक्रमण से लड़ने लगती हैं।
इस तरह MHC शरीर की सुरक्षा के लिए “पहचान प्रणाली” की तरह काम करता है। यही कारण है कि MHC का महत्व अंग प्रत्यारोपण, रोग प्रतिरोधक क्षमता और प्रतिरक्षा तंत्र के सही कार्य में अत्यधिक महत्वपूर्ण माना जाता है।

Frequently Asked Questions
What is the full form of MHC?
The full form of MHC is Major Histocompatibility Complex.
What is the role of MHC in the immune system?
MHC helps the immune system recognize which cells belong to the body and which are foreign or harmful.
How many types of MHC are there?
There are mainly two types of MHC: MHC Class I and MHC Class II.
Where is MHC found?
MHC molecules are found on the surface of most cells in the body.
Why is MHC important in organ transplantation?
MHC matching is important because differences in MHC between donor and recipient can cause organ rejection.
What is MHC Class I?
MHC Class I molecules present antigens from inside the cell to immune cells, helping detect infected or abnormal cells.
What is MHC Class II?
MHC Class II molecules present antigens from outside the cell, mainly to activate immune responses.
Can MHC affect disease resistance?
Yes, variations in MHC genes can influence how well a person fights infections and diseases.
Is MHC found in all organisms?
MHC is found in most vertebrates, including humans.
What is the function of antigens in MHC?
Antigens displayed by MHC help immune cells identify and respond to pathogens.
Conclusion
MHC, or Major Histocompatibility Complex, plays a vital role in protecting the body by helping the immune system distinguish between self and foreign substances. Its ability to present antigens makes it essential for immune responses, disease resistance, and successful organ transplantation. Understanding MHC provides deeper insight into how the body defends itself against infections and maintains overall immunity.
