Upheaval in Cellular Immunology

Immunology governs the body defence system against invading foreign particles and its associated disorders. The proper functioning of an immune system includes, detecting the pathogens and disease drivers that invades the host system and differentiate them from self-particles. These annexing microbes cause contagious diseases for which our body’s immune system contains cellular components which recognize their presence and destroys them leaving an immunological memory.

Basic immune system in most of the species is categorized into humoral and cell-mediated immunity. In humans, there are specialized barriers called blood-brain barrier and more which protects the brain from invading pathogens. Recent advancements in this cellular immunology reveal the information of signaling between the invading pathogen and host cells.
