00:00:02.000 --> 00:00:06.171
Insulin is not the pancreas’s only meal-time signal.

2
00:00:06.171 --> 00:00:10.863
Amylin is released alongside it, helping coordinate what happens

3
00:00:10.863 --> 00:00:12.428
after we eat.

4
00:00:12.778 --> 00:00:19.084
Two landmark papers in nineteen eighty-seven helped identify this

5
00:00:19.084 --> 00:00:24.690
peptide. Per Westermark and colleagues studied islet amyloid;

6
00:00:24.690 --> 00:00:30.997
Garth Cooper’s Oxford team purified and characterized its thirty-seven-amino-acid

7
00:00:30.997 --> 00:00:31.698
sequence.

8
00:00:32.048 --> 00:00:36.391
Amylin helps slow stomach emptying, limit the rise in

9
00:00:36.391 --> 00:00:40.733
glucagon after a meal, and signal fullness through the

10
00:00:40.733 --> 00:00:45.076
brain. These actions complement insulin’s role in controlling blood

11
00:00:45.076 --> 00:00:45.559
glucose.

12
00:00:45.909 --> 00:00:48.987
Native human amylin can aggregate.

13
00:00:48.987 --> 00:00:54.527
Scientists developed pramlintide by replacing three amino acids with

14
00:00:54.527 --> 00:00:59.452
proline, reducing that tendency while retaining amylin-like activity.

15
00:00:59.802 --> 00:01:05.628
In one randomized trial in type one diabetes, haemoglobin

16
00:01:05.628 --> 00:01:10.158
A-one-C fell more with pramlintide than placebo.

17
00:01:10.158 --> 00:01:14.689
The treatment difference persisted through fifty-two weeks.

18
00:01:14.689 --> 00:01:20.514
This is glucose-control evidence, not a promise of dramatic

19
00:01:20.514 --> 00:01:21.809
weight loss.

20
00:01:22.159 --> 00:01:26.638
Developed by Amylin Pharmaceuticals in San Diego, pramlintide received

21
00:01:26.638 --> 00:01:30.620
US approval as Symlin in two thousand five.

22
00:01:30.620 --> 00:01:35.099
It supplements mealtime insulin in eligible adults with diabetes;

23
00:01:35.099 --> 00:01:37.588
it does not replace insulin.

24
00:01:37.938 --> 00:01:39.514
Nausea can occur.

25
00:01:39.514 --> 00:01:44.244
Combined with insulin, pramlintide can cause severe low blood

26
00:01:44.244 --> 00:01:47.397
sugar, especially in type one diabetes.

27
00:01:47.397 --> 00:01:49.500
Careful clinical supervision matters.

28
00:01:49.500 --> 00:01:54.229
Its history sets the stage for longer-acting amylin medicines.

29
00:01:55.000 --> 00:01:56.300
Peptides in 2.

00:01:56.300 --> 00:01:57.600
World Peptide Foundation.

31
00:01:57.820 --> 00:01:59.399
Every experience matters.
