Introduction The human immune system is a complex network of cells and molecules that work together to defend the body against harmful pathogens. One of the key components of the immune system is memory B cells, which are responsible for the long-term immune response to infectious agents. Memory B cells ... Read More

Introduction The Major Histocompatibility Complex (MHC) is a group of genes located on chromosome 6 in humans that encode for MHC molecules. These molecules are essential for the immune system to identify and respond to foreign invaders such as viruses, bacteria, and other pathogens. The MHC plays a crucial ... Read More

Introduction Dendritic cells (DCs) are a type of immune cell that play a critical role in the immune system. They are responsible for identifying, capturing, processing, and presenting antigens to T cells. DCs are found in most tissues of the body, including lymphoid and non-lymphoid tissues, and are critical for ... Read More

Introduction Within the T cell population, a specific subset known as follicular B helper T cells (Tfh cells) play a crucial role in the formation and function of germinal centers, which are critical for the development of high-affinity antibodies. The immune system plays a critical role in protecting the ... Read More

Introduction Clonal deletion is a critical process in the development and regulation of the immune system. It is the process by which the body's immune system eliminates self-reactive lymphocytes, which can potentially cause autoimmune diseases. Clonal deletion is a complex process, and there are two types of clonal deletion: complete ... Read More

Introduction The Bursa of Fabricius, also known as the Bursa cloacae or simply the Bursa, is a unique organ found only in birds. It is located in the cloaca, which is the common opening for the digestive, urinary, and reproductive systems in birds. The Bursa is an important site of ... Read More

Introduction The human immune system is an incredibly complex and powerful mechanism, capable of detecting and defending against a vast array of potential threats. At the heart of this system are specialized cells called T cells and B cells, which are capable of recognizing specific foreign molecules known as antigens. ... Read More

Introduction Antigen presenting cells (APCs) are a crucial part of the immune system. They play a crucial role in initiating and regulating immune responses by presenting foreign antigens to immune cells. Accessory cells, also known as antigen-presenting cells, are a subset of immune cells that play an essential role in ... Read More

Introduction Nutrient media is a type of growth medium that is commonly used in microbiology to culture and grow various microorganisms. It is a complex mixture of nutrients that are necessary for the growth of microorganisms such as bacteria, yeast, and fungi. It can be made using a variety ... Read More

An Overview Polyacrylamide gel electrophoresis, or PAGE, is a powerful tool used by scientists to separate and analyse proteins, DNA, and RNA. This technique is widely used in various fields, including biochemistry, molecular biology, genetics, and proteomics, to study the properties of macromolecules and their interactions. Polyacrylamide Gel Electrophoresis ... Read More
