Blood immunology

Your doctor will give you a vaccine. Then they will test your blood for its response to the vaccine a few days or weeks later. How are immunodeficiency disorders treated?

The earliest written mention of immunity can be traced back to the plague of Athens in BCE. Thucydides noted that people who had recovered from a previous bout of the disease could nurse the sick without contracting the illness a second time. The study of the molecular and cellular components that comprise the immune system, including their function and interaction, is the central science of immunology.

The immune system has been divided into a more primitive innate immune system and, in vertebratesan acquired or adaptive immune system.

The latter is further divided into humoral or antibody and cell-mediated components. The immune system has the capability of self and non-self-recognition. An antigen is a substance that ignites the immune response.

The cells involved in recognizing the antigen are Lymphocytes. Once they recognize, they secrete antibodies. Antibodies are proteins that neutralize the disease-causing microorganisms.

The humoral Blood immunology response is defined as the interaction between antibodies and antigens. Immunology rests on an understanding of the properties of these two biological entities and the cellular response to both.

Besides, there are direct implications of the immune system in the infectious diseases tuberculosis, malaria, hepatitis, pneumonia, dysentery, and helminth infestations as well. Hence, research in the field of immunology is of prime importance for the advancements in the fields of n the modern medicine, biomedical research, and biotechnology.

February Learn how and when to remove this template message Clinical immunology is the study of diseases caused by disorders of the immune system failure, aberrant action, and malignant growth of the cellular elements of the system. It also involves diseases of other systems, where immune reactions play a part in the pathology and clinical features.

The diseases caused by disorders of the immune system fall into two broad categories: Other immune system disorders include various hypersensitivities such as in asthma and other allergies that respond inappropriately to otherwise harmless compounds.

Clinical immunologists also study ways to prevent the immune system's attempts to destroy allografts transplant rejection.

In fact, many of the infections acquired by neonates are caused by low virulence organisms like Staphylococcus and Pseudomonas. In neonates, opsonic activity and the ability to activate the complement cascade is very limited.

Phagocytic activity is also greatly impaired in newborns.

This is due to lower opsonic activity, as well as diminished up-regulation of integrin and selectin receptors, which limit the ability of neutrophils to interact with adhesion molecules in the endothelium. Their monocytes are slow and have a reduced ATP production, which also limits the newborn's phagocytic activity.

Although, the number of total lymphocytes is significantly higher than in adults, the cellular and humoral immunity is also impaired. At birth, most of the immunoglobulin present is maternal IgG. Some IgA is provided by breast milk.

These passively-acquired antibodies can protect the newborn for up to 18 months, but their response is usually short-lived and of low affinity.

If a child is exposed to the antibody for a particular antigen before being exposed to the antigen itself then the child will produce a dampened response.

Passively acquired maternal antibodies can suppress the antibody response to active immunization. Similarly the response of T-cells to vaccination differs in children compared to adults, and vaccines that induce Th1 responses in adults do not readily elicit these same responses in neonates.

This can be the reason for distinct time frames found in vaccination schedules. Oestradiol usually begins to act around the age of 10 and testosterone some months later.Immunology and Blood Groups An infectious disease is caused by pathogens, where they are said to be parasitic.

Pathogens are organisms that live on or in their host, and gain nutrients from that host. Human blood can be classified into different blood group systems, e.g. ABO blood group, MN blood group and Rh blood group.

What are immunology and serology?

All of these blood groups in man are under genetic control, each series of blood groups being under the control of genes at a single locus or of genes that are closely linked and behave in heredity as though they were at a single .

What are immunology and serology? Immunology is the study of the body's immune system and its functions and disorders. Serology is the study of blood serum (the clear fluid that separates when blood clots). Immunology and serology laboratories focus on the following: Identifying antibodies.

Nontraditional roles for the hemostatic system in the vessel wall. Module 2 – Immunology and Blood Groups Page 3 The immune system has two main components: Non-specific immune response o Physical, chemical and cellular defences that prevent microbes from entering the body o Present from birth.

o A quick-response system effective against a wide range of pathogens and foreign substances. Infectious Disease Tests Infectious diseases can be transmitted in a number of ways.

If you've been exposed, you want to know quickly, as diagnosis and treatment can help prevent further transmission.
