Immune System
This category is for questions about how our bodies identify and fight off disease, infection or pathogens through specialized cells, tissues and organs. The system that does this is called the immune system. It produces antibodies which recognize intruders and neutralizes potentially pathogenic organisms or substances.

What type of pathogen has no cure?
They are some types of viruses that don't have any cure.One of them it is Ebola virus.
Is the principle of northern southern and western blotting is same?
yes the principle of all the three is same .the basic difference lies during probing nd detection .in case of southern blotting DNA is used in nothern rna and in case of western blotting antibodies are ued

PLEASE TELL ME !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
What is the difference between a class I MHC mechanism vs a class II MHC mechanism?
The Class I MHC molecules process endogenous(intracellular) peptides/antigens whereas the Class II process exogenous(extracellular) peptides/antigens.
The Class I molecules are assembled and located in the ER whereas the Class II are assembled in the ER but located in the endosomes.
When extracellular peptides are taken into the cell via receptor mediated endocytosis or phagocytosis, they will be transported into the endosomes and get degraded. This will enable the peptide generated to be loaded onto the Class II molecules.
For Class I, when a bacteria or virus infect a cell, they will replicate and produce proteins. These proteins will be ubiquitinated and degraded by the proteasome. This smaller peptides can then be transported into the ER via the TAP transporters, that are complexed with the Class I molecules, to be loaded onto the Class I molecules.
4 ways you can acquire immunity of antibodies?
Active (your body produces the t-cells and b-cells):
Natural- by means of infection
Artificial -
Passive- (develops in another person and is transferred):
Natural - maternal
Artificial - immunization
What are your bodys non specific defenses against pathegons?
Non specific defenses against pathogens include intact skin, temperature, neutophils, macrophages, and natural kills cells.
What confers high titer of antibodies?
high titer of Antibodes in a person means that person or animal is exposed to disease . this titer would be 7 to 9.if titer is upto 4 or 6 well means animal or the human is vaccinated.
Does macrophage have a nucleus?
Yes, phagocytes have a nucleus. Their nucleus is a bit different though, and is lobed, to allow room for the process of phagocytosis. This answer may be a little late, but I hope that this helps

There is a little more to it, but a basic way to define is: In the immune system it's a mechanism used to remove pathogens and cell debris.
Assessment of immune complex in tissues?
The value of three immune complex assays in the management of systemic lupus erythematosus: an assessment of immune complex levels, size and immunochemical properties in relation to disease activity and manifestations.
What would no longer be possible if a disease resulted in the death of all your T lymphocytes?
You would no longer be able to fight of infections. T lymphocytes or T cells help to tag and destroy foreign invaders such as bacterium or viruses. Destruction of which would cause immune system failure.
Causes of T cell death could be HIV infection, or excessive radiation exposure.
What is a radiopaque foreign body?
A radiopaque foreign body is an object that does not allow X-rays to pass through, making it visible on radiographic images. Common examples include metal items, glass, or certain types of plastic. These objects can be detected during medical imaging, which is crucial for diagnosing and managing cases where foreign bodies are suspected in the body. Identifying such objects can help guide appropriate treatment and removal methods.
