Parallelism between the intestinal immune system and the respiratory immune system

In this article, I briefly describe the parallelism between the intestinal and respiratory immune systems. The respiratory tract The respiratory tract is responsible for breathing and exchanging oxygen and carbon dioxide between the body and the environment. It is divided into upper respiratory tract and lower respiratory tract. It is exposed directly to the external … Read more >>

Common intestinal diseases

In this article, I briefly describe the common diseases associated with the intestine. Inflammatory bowel disease, Crohn’s disease, and Celiac disease are common intestinal diseases. Our intestinal immune response and diseases The immune system’s response to both commensal and pathogenic microbes is not without cost. Even when inflammation successfully eliminates pathogens, it can still damage … Read more >>

Intestinal immunity can initiate both type 1 and type 2 immune responses

In this article, I briefly describe the type of immune responses of our intestines. Intestine and pathogens Our intestinal immune system responses to specific pathogens reveal extra complexities. There are many bacteria and worms causing diseases in our bodies. Our immune system shows different types of responses to worms and bacteria. Bacteria get a type … Read more >>

The intestinal immune system recognizes and responds to pathogens

In this article, I briefly describe how the intestinal immune system recognizes and responds to pathogens. Intestine and pathogens Most organisms that live in harmony with us are not harmful and help create a tolerant environment in the intestines. The gut immune system ensures a safe separation between the epithelial surfaces and even the beneficial … Read more >>

Various innate and adaptive cell types promote immune homeostasis in the intestine

In this article, I briefly describe how various innate and adaptive cell types promote immune homeostasis in the intestine. Our gastrointestinal tract It is a tube-like structure running from the mouth to the anus. The gastrointestinal tract maintains our commensal microbiome and regulates local and systemic immune responses. Our gastrointestinal tract deals with billions of … Read more >>

Small and large intestines possess different immune system

In this article, I briefly explain the disparity in immunity in small and large intestines. Distinct immunity in small and large intestine The small and large intestines manage their relationship with the microbiome by sharing general strategies. However, the physiology of each section is distinct, as are the microbial communities and immune cells that inhabit … Read more >>

Negative regulation of B-cell activation

In this article, I briefly describe the negative regulation of B-cell activation. B-cell activation and control Presentation of antigens via MHC and receiving co-stimulatory signals (CD40-CD40L) from TH2 cells, results in the activation of B cells (figure 1). Following activation, B cells undergo cycles of mutation and selection to produce high-affinity memory B cells and … Read more >>

Types of associations among soil microorganisms

In this article, I briefly describe the types of associations among soil microorganisms. Microbial ecosystem The total microbial flora along with the soil’s physical composition and physical characteristics, includes the microbial ecosystem. It is the sum of the biotic and abiotic components of soil. The soil microorganisms exhibit many different types of interactions or associations. … Read more >>

Application of gene cloning in medicine

In this article, I briefly describe the application of gene cloning in medicine. Gene cloning Gene cloning begins with isolating and inserting a specific gene into a vector. The vector is then introduced into a host organism. It makes multiple, identical copies of a particular gene or DNA segment. The host organism then replicates, producing … Read more >>

Application of gene cloning in producing recombinant proteins

In this article, I briefly describe the application of gene cloning in producing recombinant proteins. Gene cloning It is a molecular biology technique that makes identical copies of a particular piece of DNA, or gene. A target gene is introduced into a circular piece of DNA called a plasmid in a cloning experiment. The plasmid … Read more >>
