Question
Match each antigen with its potential effect on the immune system. Note: each answer choice may be used more than once.
1) Beneficial (appropriate) response by immune system if activated
2) Harmful (inappropriate) response by the immune system if activated
_______thyroid gland
_______Amanitas spp. (fungi)
_______Zika virus
_______shellfish
_______transplanted cornea
_______pancreas
_______Escherichia coli (bacterium)
_______stem cells
_______ Leishmania major (parasite)
_______copper bracelet
_______hookworm
(please answer option 1 or 2 for each one!)
Explanation / Answer
Ans. Beneficail response when the thyroid gland is activated is that thyroid gland release TSH hormone . The TSH hormone when used by the cells of immune system in humans and mice to agroup of monocytic cell and lymhocytes , primarily the dendritic cells , macrophages and subset of native cells.
It harmfull response to the immune system is that it releases autoantibody. It result in the autoimmune disease . ATD Is an archetypal organ specific autoimmune disease that is characterised by the production of thyroid autoantibodies which act as the pathogens.
2. Beneficial role of the fungi is that they activate the innate immune response by dendritic cells and phagocytosis . They also develop the reactive oxygen species and develop the adaptive immunity.
Harmfull role is that they kill the neutrophils and macrophages.
Zika virus control the flavivirus . It is its beneficial role . It depletes the neural progenitors in human cerebral organoids through activation of the innate immune receptor TLR3.
E. colli blocks the innate immune system.
It beneficial role is that the regression of the immuno dependent tumour . It also increase the IgA secretion and B lymphocytes secretions.
