Cell Mediated Immunity
In the earlier article, we discussed the Humoral immunity. Conversely, this article is about the remaining aspect of the Adaptive immune system, i.e. Adaptive Immune response via Immune Cells. In this article, we will explore the types of cells responsible for cell mediated adaptive immunity. We will also look at their respective roles. When talking… Continue reading

Humoral Immunity
The human body can kill invading microbes in various ways. One of which is making them laugh to death (that was a joke). The term “humoral” comes from the Latin word “humor,” meaning fluid. Historically, it referred to bodily fluids believed to govern human health. The idea dates back to ancient Greek medicine, which believed… Continue reading

Understanding the Complement System
The complement system, comprising circulating and membrane-associated proteins, plays a crucial role in defending against microbial invaders. Comprising three main components—complement factors, complement receptors, and regulatory proteins ;the system orchestrates a cascade of responses to combat pathogens effectively. Brace your self because you’re going to see a lot of flow charts in this article. For… Continue reading

Innate Immunity
Innate immunity, often referred to as natural or non-specific immunity, constitutes the body’s first line of defence against pathogens and antigens. Antigens, substances capable of triggering immune responses, come in various forms, such as bacteria cell wall lipopolysaccharides and pollen, encompassing proteins, glycoproteins, lipoproteins, and more. . The immune system identifies these threats through pattern… Continue reading

Exploring the Components of Immunity
In immunology, understanding immunity means looking at its different parts, including innate and adaptive responses. Let’s start on a journey through the key players and processes that protect our bodies against germs. Innate Immunity: The First Line of Defence Barriers The body many layers of defence to fight off pathogens.. Mechanical barriers include intact skin… Continue reading
