1
00:00:02,200 --> 00:00:07,961
KPV is only three amino acids long, but its
research story connects hormone

2
00:00:07,961 --> 00:00:11,312
biology, immune signaling, and the intestinal
lining.

3
00:00:11,522 --> 00:00:17,167
Its name comes from lysine, proline, and valine:
the final three amino acids of alpha

4
00:00:17,167 --> 00:00:23,416
melanocyte stimulating hormone, a natural peptide
involved in several biological processes.

5
00:00:23,611 --> 00:00:28,959
By 1989, Melanie Hiltz and James Lipton at the
University of Texas Southwestern Medical

6
00:00:28,959 --> 00:00:34,222
Center in Dallas had reported that this small
fragment reduced experimentally induced

7
00:00:34,222 --> 00:00:35,544
swelling in mice.

8
00:00:35,732 --> 00:00:39,836
That gives KPV more than thirty-five years of
published research history.

9
00:00:39,977 --> 00:00:41,818
The gut became an important focus.

10
00:00:42,020 --> 00:00:47,452
In a 2008 study, Guillaume Dalmasso, Didier Merlin,
and colleagues at Emory University

11
00:00:47,640 --> 00:00:51,101
investigated a peptide transporter called PepT1.

12
00:00:51,287 --> 00:00:55,892
Think of this transporter as a doorway into certain
intestinal and immune cells.

13
00:00:56,077 --> 00:01:01,347
In laboratory experiments, it carried KPV inside,
where researchers observed reduced

14
00:01:01,347 --> 00:01:06,371
activity in inflammatory signaling pathways,
including nuclear factor kappa B.

15
00:01:06,453 --> 00:01:11,446
The same research also found reduced inflammation
in two mouse models of colitis.

16
00:01:11,643 --> 00:01:16,613
A separate German team reported earlier recovery,
improved weight regain, and less

17
00:01:16,613 --> 00:01:19,803
inflammatory damage in additional mouse studies
published that year.

18
00:01:20,082 --> 00:01:24,513
These findings explain the interest: could a tiny
fragment of a natural hormone help

19
00:01:24,513 --> 00:01:28,436
regulate excessive inflammation, particularly in
the digestive tract?

20
00:01:28,585 --> 00:01:30,322
The results are preclinical.

21
00:01:30,439 --> 00:01:35,843
Human cell experiments are not human treatment
trials, and mouse colitis is not proof of

22
00:01:35,843 --> 00:01:39,860
benefit for people with Crohn's disease or
ulcerative colitis.

23
00:01:40,054 --> 00:01:43,068
KPV is not an FDA-approved treatment.

24
00:01:43,226 --> 00:01:49,461
Effective human formulations, clinical benefits,
and long-term safety still require investigation.

25
00:01:49,618 --> 00:01:54,712
Its scientific appeal is clear: three amino acids,
a cellular doorway, and a continuing

26
00:01:54,712 --> 00:01:57,164
search for more targeted control of inflammation.

27
00:01:57,406 --> 00:01:58,773
World Peptide Foundation.

28
00:01:58,966 --> 00:02:00,050
Peptides in 2.

29
00:02:00,177 --> 00:02:01,626
Every experience matters.
