I, Swagatika Sahu (author of this website), have done my master's in Biotechnology. I have around twelve years of experience in writing and believe that writing is a great way to share knowledge. I hope the articles on the website will help users in enhancing their intellect in Biotechnology.

Replacement therapy treats immunodeficiency disorders

by

In this article, I briefly describe various replacement therapies that treat immunodeficiency disorders. Treatment for immunodeficiencies There are many treatment options available for immunodeficiency disorders, but no reliable treatment is available for them. Besides using antimicrobial agents or resorting to the extreme measure of complete isolation from opportunistic pathogens, immunodeficiencies can be managed through replacement … Read more >>

Immunodeficiency disorders can lead to the development of autoimmunity

by

In this article, I briefly describe immunodeficiency disorders that disturb immune regulation, which can lead to the development of autoimmunity. Deficiencies in T-cell tolerance lead to autoimmunity The adaptive immune system recognizes and eliminates foreign antigens. It also has to recognize self-MHC proteins and suppress reactions to self-antigens in the host. The induction of tolerance … Read more >>

Defects in innate immune components result in deficiency and diseases

by

In this article, I briefly describe how defects in innate immune components result in diseases and deficiency. Innate immune defects Disorders in myeloid cells or in components of the complement activation pathways lead to innate immune defects. Many of these defects lead to lesser phagocytic cells or defective phagocytic processes. These processes may have defects … Read more >>

Primary immunodeficiency results in different immunodeficiency syndromes

by

In this article, I briefly describe how primary deficiency leads to different immunodeficiency syndromes. Primary immunodeficiency Primary immunodeficiency is generally a birth defect and causes many health issues in early life. Immunodeficiency disorders are minor or life-threatening. Primary immunodeficiency diseases have provided immunologists valuable insights into the critical roles of specific proteins and cellular processes … Read more >>

Severe combined immunodeficiency (SCID) interrupts with T-cell and B-cell responses

by

In this article, I briefly describe severe combined immunodeficiency (SCID) and its interruption with T-cell and B-cell responses. Combined immunodeficiencies The diseases that result from impaired T-cell function or absence of T cells, combined with some disruption of antibody responses are known as combined immunodeficiencies. T helper cells (TH cells) are needed for complete activation … Read more >>

Primary immunodeficiencies are mostly hereditary

by

In this article, I briefly describe primary immunodeficiencies, which are mostly hereditary and may be minor or life-threatening. Primary immunodeficiency The condition is known as immunodeficiency when our immune system fails to protect us from diseases. Primary immunodeficiency results from an inherited genetic defect. This is generally a birth defect and causes many health issues … Read more >>

Improvement in vaccine immunogenicity and enhancing immune response

by

In this article, I briefly describe the methods to improve vaccine immunogenicity and enhance the immune response. Vaccines A vaccine is a biological preparation that gives immunity to some infectious diseases. The administration of vaccines is called vaccination. Edward Jenner was an English physician and scientist who pioneered the concept of vaccines including creating the … Read more >>

Nucleic acid vaccines give a broad and long term immune response

by

In this article, I briefly describe nucleic acid vaccines, their mechanism of working, and the broad and long-term immune response in humans. Nucleic acid vaccines The vaccines which use genetic material from a harmful pathogen to stimulate an immune response are called nucleic acid vaccines. These vaccines can contain either DNA or RNA. This genetic … Read more >>

Recombinant vector vaccines retain many advantages of live attenuated vaccines

by

In this article, I briefly describe the recombinant vector vaccines and their advantages over live attenuated vaccines. Live attenuated vaccines Attenuation is a process, where microorganisms lose their ability to cause a significant disease. In other words, attenuation takes away the pathogenicity of microorganisms. Attenuation can be achieved when a pathogenic virus or bacterium is … Read more >>

Subunit vaccines– vaccines from purified macromolecules

by

In this article, I briefly describe the types of subunit vaccines. Purified macromolecules as vaccines Attenuated or inactivated whole-organism vaccines carry certain risks, prompting the development of alternative options that utilize specific purified macromolecules from pathogens. Currently, three main types of such vaccines are used: capsular polysaccharides, toxoids, and recombinant microbial antigens. Capsular polysaccharides The … Read more >>
