One of the most important response systems we have as animals is that of our immune system and its response to invading pathogens, antigens, and it’s rejection of foreign material. The details behind the functioning of this response went largely overlooked from a genetic perspective primarily until the early 1970’s however. Baruj Benacerraf with his collaborators Jean Dausset and George Davis Snell explored just this, publishing a series of findings that lead to the “…discovery of the major histocompatibility complex genes which encode cell surface protein molecules important for the immune system 's distinction between self and non-self” ("Baruj Benacerraf - Biographical") which eventually lead to their winning and sharing of the Nobel Peace prize in Physiology or Medicine. Early that decade he and Hugh O. McDevitt published an article on the Histocompatibility-Linked Immune Response Genes. Working from the discovery of autosomal genes correlating to antibody synthesis with dominant phenotypes of capable of producing the responding antibodies to an antigen and responses to “non-self” cells such as grafts, their studies explored injecting guinea pigs with a variety of antigens to identify distinct immune response genes. To clarify, The American Heritage® Science Dictionary defines histocompatibility as “A state or condition in which the absence of immunological interference permits the grafting of tissue or the transfusion of blood without rejection”. Thusly this
“Humoral immunity is a type of immune response that depends on antibodies.” The response begins when a pathogen binds to a B cell. The B cell will engulf the pathogen and display a part of the antigen on its exterior. Once a T cell is exposed to the antigen-presenting B cell, the T cell will release proteins to activate the B cell. Now that the B cell is activated, it will produce antibodies to cause the pathogens to clump together. In the last stage of humoral immunity, phagocytes will engulf and destroy the pathogens.
This, according to the clonal selection theory, the immune system functions on the “ready-made” rather than the “made-to-measure” principle. The question of how an animal makes so many different antibodies there for become a problem of genetics rather than one of protein chemistry” (Bowden 1006). This means that genetics determine how well the immune system works and this the key to figuring out a way to boost the immune system to help fight of infections and diseases before they even begin to weaken and infect the whole body. If someone decided they wanted to be immune to a snake bite or HIV the only thing that would have to be done is find one person just one that is immune and clone that person gene and add it to the other person who also wants to be immune to a certain disease, physical or chemical problem. “Scientist have grown replacement organs for sheep, rats and rabbits using the animal's own cells and alb molds to help the tissue take shape a technique that could be used someday to make spare parts for
The innate and adaptive immune response start with exposure to an antigen in the epithelium of
This is immunity that is acquired by the transfer of anitbodies from one individual to another. For example, from a mother to her offspring.

Have you ever wanted a pet guinea pig or needed tips about a guinea pig? If so, then you should keep reading. There is a lot of interesting facts you should know about raising these animals.
Do you know facts about guinea pigs? I know they are rodents, and they need Vitamin C, they are mammals, and they have black or brown eyes. I want to know what food they eat, what are the kinds of guinea pigs, what do their sounds mean, and most of all, facts about albino guinea pigs.
Explain the involvement of immune cells (B, C, T, antigen presenting cells and immune complex).
According to Rosenberg (1988), the field of immunotherapy has become an area of significant and increasing interest within the field of medical science, prompted by the recent advances in knowledge of both biotechnology and cellular immunology. The field of immunology has produced revolutionary developments such as vaccines, which have prevented and decreased the occurrence of numerous infectious diseases over the past two centuries (Oviedo-Orta et al. 2013). Vaccine development has in turn combined immunology and drug design, resulting in a great deal of innovation over the last four decades endeavouring to expand the benefit of immunology past vaccines against foreign pathogens, and towards the treatment of chronic debilitating diseases.
Urinary tract Infections – Female Guinea Pigs can get a condition known as cystitis, inflammation of the bladder, which can lead to blood in the urine or difficulties urinating.
Considering that I had twenty-six guinea pigs, I would do it again in a heartbeat. I think guinea pigs are cuter and nicer than hamsters.they play with you and cuddle with you. They might require more, but there's nothing I wouldn't do for my pet. Nothing, is as cute as a guinea pig running around their cage and sleeping on your chest.
Miniature swine are the animals selected for the study of mixed hematopoietic chimerism in pigs. These animals have been bred to develop homozygous and recombinant lines for MHC differentiating the genes for MHC class I and class II, known as swine leukocyte antigen (SLA) (Pennington et al. 1981; Lunney and Sachs 1995).
Comparison of protective Antibody response in guinea pigs immunized with Wild type (Wt) BoHV-1 and ΔgE BoHV-1 mutant virus vaccine
When mammalian DNA is injected into the body, dendritic cells are not stimulated. Moreover, it also failed to elicit appreciable antibody response even when it coupled with a protein carrier and presented in adjuvant (Madaio et al., 1984). This failed action is quite the opposite of animal disease models that are stimulated by immunization with protein auto-antigens such as experimental allergic encephalomyelitis or collagen-induced arthritis, inferring that DNA is different from other biomolecules in its immunological properties. Various studies, including from our lab (Dixit et al., 2005; Tripathi et al., 2014) as well as from others (Al Arfaj et al., 2007) propose that the DNA molecule undertake structural changes leading to the formation of new epitopes or neo-epitopes that are recognized as foreign by the immune system and are able to bring out antibody responses. However, when single stranded DNA is used for immunization, it can bring a restricted antibody response, and other helical nucleic acid species including double stranded RNA, RNA-DNA hybrids, carcinogen or drug modified DNA or complexes of DNA with proteins that can bind DNA are considered to be effective immunogens (Stollar, 1975; Anderson et al., 1988; Desai et al., 1993; Moinuddin and Ali, 1994; Dixit et al., 2005; Khan et al., 2006; Tripathi et al., 2013). Due to the presence of distinctive sequence motifs, bacterial DNA can induce the immune system to generate antibodies to sequential rather that backbone
The scientific community, none more than the field of biology, is constantly advancing technology and society while being influenced by them at the same time. The case of antibodies is no exception. Antibodies have had a pivotal role in disease therapy and vaccine design which has been able to save the lives of millions. This paper will introduce and review antibodies and their relevance to biological advancement as well as the development and application of the research into society. It will also demonstrate how the field of biology, technology and society are in an ever changing and diverse landscape.
