Journal of Allergy & Therapy is one of the top open access journals, it strives to publish information on the most recent advancements in the field of allergy in the form of original papers, review articles, case reports, short communications, etc. High impact factor contributions that are excellent and new are anticipated to enhance citations.

The immune system is a network of biological processes that protect an organism from disease. It recognizes and responds to a variety of pathogens, from viruses to parasites, objects such as cancer cells and tree debris, and distinguishes them from the organism's own healthy tissue. Many species have two major immune system subsystems. The innate immune system provides a pre-configured response to a variety of situations and stimuli. The adaptive immune system provides a tuned response to each stimulus by learning to recognize previously encountered molecules. Both use molecules and cells to perform their functions. When bacteria like viruses enter your body, they attack and multiply, this is called an infection. Infections cause illnesses that make you sick. Your immune system protects you from illness by fighting off bacteria. The immune system is complex and ubiquitous.

There are many cell types that circulate throughout the body or are present in specific tissues. Each cell type plays a unique role in different ways of detecting problems, communicating with other cells, and performing their functions. By understanding all the details behind this network, researchers can optimize their immune response to address specific problems, from infection to cancer. Innate immunity is to protect you by nature, it is the first line of defense of your body. This includes barriers such as skin and mucous membranes. They prevent contaminants from entering the body. It also contains cells and chemicals that can attack foreign substances. Active immunity, also called adaptive immunity, develops when you are infected with or vaccinated against a foreign substance. Active immunity is usually long-lasting. For many diseases, it can last your entire life. Passive immunity happens when you receive antibodies to a disease instead of making them through your own immune system. For example, newborn babies have antibodies from their mothers. People can also get passive immunity from blood products that contain antibodies.

This type of immunity gives you immediate protection. But it only lasts for weeks or months. Innate immune cells use pattern recognition receptors to recognize the molecular structures produced by pathogens. They are proteins expressed primarily by cells of the natural immune system such as dendritic cells, macrophages, monospheres, neutrophils, epithelial cells, and distinguish between two classes of molecules: associated with microbial pathogens. Damage-related molecular patterns associated with pathogen-associated molecular patterns Accompanied by components of the host cell released upon cell damage or cell death
