Abnormality of Sweat Glands in Cystic Fibrosis

Please read and agree to the disclaimer before watching this video.
. Cystic fibrosis is the most common hereditary disease which causes death in the United States, by the age of 20 or 30.
Dr. Mobeen Syed discusses the abnormalities in the genes which lead to cystic fibrosis.
The three genes responsible for phenylalanine production are located on the chromosome no. 7. These genes are also responsible for contributing proteins to CFTR complex. The CFRT complex is a transmembrane regulator chloride channel.
***In cystic fibrosis, the phenylalanine genes undergoes deletion.
***An abnormality in the phenylalanine genes causes abnormal production of CFTR complex.
The improperly folded protein complex (an abnormal CFTR complex) degrades in the Golgi apparatus.
***Normally what happens is that chloride, sodium, and water (small amount) are reabsorbed from the sweat when thrown out of the sweat glands in the sweat canaliculi. Result is that sweat becomes hypotonic.
On the other hand, chloride, sodium, and water are not reabsorbed from the sweat when the CFTR complex is abnormal. The result is that the sweat becomes hypertonic when released.
***The release of the hypertonic solution causes heat exhaustion and dehydration.
The following topics have discussed in the video:
* Definition of cystic fibrosis
* Normal sweat production
* Abnormality in the sweat gland
* Production of hypertonic sweat
* Effect of hypertonic sweat on the body ...

Getting ready for my NCLEX. This video gave me a much better understanding of the sweat test & what happens in the glads with patients who have CF. Thank you!!!

[@elip8604]

Thank you!!!! I Finally understand it!!

[@AB-xd8ft]

thank you very much i needed this video

[@54kishanpatel26]

Thanks u sir for explaining about Sweat chloride mechanism...which is different than pulmonary chloride mechanism 😊

[@mukhtarmaxamud5968]

thank you Dr

[@dpledford1]

As an undergrad I learned that Doctors used to lick their patients to see if they were salty with this disease. I never knew why. It’s cool to understand.

Thanks

Always best sir it is autosomal recessive disorder cftr gene is parsent on chromosome no. 7 cftr is pump related disease ABC classs pump on plasma membrane cl channel are not functional.
Your presentation is fabulous sir

[@dpledford1]

I am curious that in the golgi, is it a ubiquitin process that degrades the phenylalanine, using proteosomes?

[@abdulbaryalhalimi2318]

Exactly my question

[@dpledford1]

@@abdulbaryalhalimi2318 I will try to find out!

[@workorwork4666]

love u

How to control it plz suggest me😔😔
