Abstract:
Mycoplasma hyopneumoniae is the pathogen causing swine mycoplasmal pneumonia. The lack of well-established animal models of M. hyopneumoniae infection has delayed the progress of M. hyopneumoniae-related anti-infection immunity studies. This paper reviews the inflammatory response, the recognition of M. hyopneumoniae by the innate immune system, and the role of innate immune cells, complement system, antimicrobial peptides, autophagy, and apoptosis in M. hyopneumoniae infection. The aim was to elucidate the important roles played by the components of the innate immune system in the control of M. hyopneumoniae infection, and prospect key research directions of innate immune response of M. hyopneumoniae infection in the future.
Insights
This review highlights the innate immune system's role in controlling swine mycoplasmal pneumonia caused by Mycoplasma hyopneumoniae. Understanding these responses is crucial for developing effective anti-infection strategies.
Area of Science:
- Veterinary Immunology
- Infectious Diseases
- Swine Health
Background:
- Mycoplasma hyopneumoniae causes significant respiratory disease in pigs, leading to swine mycoplasmal pneumonia.
- Progress in understanding M. hyopneumoniae immunity is hindered by a lack of robust animal models.
Approach:
- This review synthesizes current knowledge on the innate immune response to M. hyopneumoniae.
- It examines inflammatory pathways, pathogen recognition, and the involvement of immune cells, complement, antimicrobial peptides, autophagy, and apoptosis.
Key Points:
- The innate immune system employs diverse mechanisms to combat M. hyopneumoniae.
- Innate immune cells, complement, antimicrobial peptides, autophagy, and apoptosis are critical in controlling infection.
- Inflammatory responses are central to the host's defense against M. hyopneumoniae.
Conclusions:
- Elucidating the innate immune system's role is vital for developing novel anti-M. hyopneumoniae therapies.
- Future research should focus on key directions in innate immune response to M. hyopneumoniae infection.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
