Senotherapeutics are therapeutics strategies that target cellular senescence. These strategies can work by killing senescent cells (senolytics), inhibiting the proinflammatory secretory phenotype of senescent cells (senomorphics) or by activating our endogenous senolytic systems (immune surveillance). But what even are senescent cells, how do senolytics work, and what current human clinical trials provide supporting data?
In this video we will begin by discussing what senescent cells are, what causes a cell to become senescent and why targeting senescent cells may provide therapeutic potential for aging and age-related diseases. We will then look at the three main branches of senotherapeutics, senolytics vs. senomorphics and what future work is being conducted to evaluate the safety and efficacy of these strategies.
So, in many ways you could consider this video my ultimate guide to senotherapeutics! :D

So, what do you think, exciting times to come? :D
p.s I like pink trees :D
Pretty much! :)
It's exciting now! 😺
Awesome potential: D&Q were just the appetizer

I can't believe how excited I get, when I see you post a video. It's not just fluff, your videos are very informative. The information here is revolutionary in the field of human health. You make it easy for the average person to understand without dumbing it down.
It all starts with health for each one of us. Get healthy and it will improve your finances and relationships.
Thank you for these postings. I understand the topics better because of you. Appreciative here!
Thanks John! 😊
@@TheSheekeyScienceShow Your work is reaching people...
Your use of visuals is excellent & helps to understand this complex area.
Brilliant work! Definitely exciting times to come. Thanks for explaining this topic with such clarity.
Thank you! 😊
I like your mixture of scientific jargon with lay explanations. Thank you,
Thank you for explaining science behind aging so clearly. I enjoy watching your videos very much.
Thank you!! 😊
well-done and educational! Thank you
Gee!
You talked about wound healing, this indicates that cells used for temporary structures like scars and scabs will become senescent when they have completed their work and then the SASP will signal that they can be removed. Also with baby teeth, these cells will become senescent and be removed when it's time to produce adult teeth. So it seems that the SASP and senescent cells are involved with the process of programmed growth as determined by the DNA.
As a 65 year old who semi-buys into Kurzweil's idea that using current knowledge will get us another 10 years of life where new knowledge will then buy us another 10, etc... I'm soaking up all the info I can about anti-aging and applying what makes sense. I already use intermittent fasting, aerobic and anaerobic exercise, NAD precursors, a CD38 inhibiter, a ketogenic+greens and berries diet, and based on what I'm learning now I will also add: a few days a month of Quercetin and Fisetin for their synolitic properties, and alternately on non-strength training days I will use berberine for its senotheraputic properties. (I still want mTor activation on my strength-training days!) If this regimen sounds counter-productive please let me know!
Impressive! Do you do hiit also? And how plant-based are you? Do you have other practices like lengthening, breathing, meditation, etc?
@@DIYDSP I'm plant-friendly... but still love my occasional steak on weight-training days. I'm adding a primal-movement routine to my workout but that's about as close to yoga as I get, lol. For HIIT, I bike in a hilly area so the uphill sprints definitely qualify! (A fun workout you actually do always beats a better workout that you avoid.) As for meditation... does an occasional alcoholic beverage qualify? :) Anyway - I''ll be watching your channel as you continue to learn and teach. Thanks!
Greetings from Singapore. May I ask you what doses of Quercitin and Fisetin you are using ? I am 67 years old and doing something similar to you. Did you know that you can obtain sub-lingual NMN 250mgs from Uthever and also 20mgs sub-lingual NADH from ENADA ?
I've been taking Tru Niagen ( NR ) for almost the past 20 days. Intermittent fasting now and then, almost absolutely sedentary, vegetarian lifestyle, B-Complex, Astaxanthin, Shilajit, Omega 3, Zn+Cu, D3+K2 are the other supplements. From research it seems like we need to take Fisetin along with NAD precursors so they remove the senescent cells and ensure NAD that we supplement don't get leaked to the senescent cells and wasted. I will need to add Quercetin as well and start fasting like 3 days a month if not 7 days in 3 months.
It's been two years where is the earth shattering knowledge the hustler Kurzweil promised? Nada friend
Great video many thanks!!
Very well put! Keep it up
Thank you so much!!!
Hey Sheekey, one question, what kinda program for your notes do you use?
P.S. thank you for your amazing content!
Do a video on NRF2 please
Thanks for sharing
hi thanks for the video, i am wondering if you are still taking NMN, and do you see any effects at all?
Approximately what percentage of cells by major organ are senescent in say an 80 yr old? Another great timely summary.
Where do you put NMN, NR, Resveratrol and other NAD and Sirt1 boosters?
What about strategies to rejuvenate old cells and prevent/delay their eventual demise into senescent cells? How many approaches are available to potentially reduce senescence? Supplement approach would be especially of interest to me (e.g. NR/NMN to increase NAD+ which in turn help Sirtuins to repair DNA?)
Should we do a senolytic hot and run once a month followed by two days fast?
I take Quercetin n bromelain.
Sorry if this is asked before, but why does the body even have the mechanism to allow cells to become senescent rather than simply using apoptosis in every case when a cell isn't functioning properly? I ask because: Could there be any unintended side effects of totally eliminating cells becoming senescent? Or is it simply an evolutionary mistake? Are all senescent cells bad?
Yeah, a great question (and from my biased interest, how p53 activity coordinates such a different response)! You will be interested in paracrine induced senescence. There was also a paper i covered last year (removing senescent cells bad?) whereby removal had deleterious effect, suggesting that cells, even though senescent may serve structural/regenerative impact that is not possible is a cell just dies
Is there any information about how fasting or fmd's can cause apoptosis of senescent cells? And if so, what sort of time scale is required for optimum results? Thanks. Good video.
So as i mentioned at the end this has been surprisingly understudied... There is some evidence for caloric restriction and reducing SASP gene expression (anyone correct me if I'm wrong), but yeah this is a question i would also like to know the answer to! 😊
@@TheSheekeyScienceShow OK, thank you. Hopefully we'll be able to find out more soon.
So far, what I understood is that intermittent fasting will keep the cell healthy for a longer time and so avoiding the need of it's replacement, thus delaying the onset of senescence
Seems like a intracellular intervention, while to deal with already senescent cells an extracellular approach would be needed
@@r.guerreiro140 Yes, autophagy is intracellular, and I guess apoptosis would require an extracellular approach, as you say, but that doesn't mean longer term fasting couldn't accomplish that. Maybe.
@@davidwelburn That's what seems to me as well
Ty
how about sulforaphane? please... :)
Would it make sense to activate mechanism 3 (immune surveillance) with an mRNA vaccine? Anti-aging vaccine?
There is definitely interest in using this approach for treatment beyond immune activation
@@TheSheekeyScienceShow sounds like another great idea for a video 😁
Thank u girl
Yes 🔥
Do you have a place where you deposit a zoomed-out version of your drawing for each video?
I was uploading them to patreon
@@TheSheekeyScienceShow sounds like I need to sponsor you. You are doing really great work btw! : )
Which synolytics work best?
What is the editor you use? Great videos.
Editor = me 😊
@@TheSheekeyScienceShow Software?
A Xenomorph is something out of the movie 'Alien'
Why would senescent cells express anti-apoplectic proteins if cellular senescence evolved as an anti-cancer mechanism? It seems more likely that the senescent secretory phenotype expression evolved to signal for destruction cells that have become excessively anti-apoptotic. ??
That's a very interesting question!! Bad design and hence the antagonostic pleiotropy of the anti-cancer and then pro-cancer influence. I don't think we have a clear answer for this yet
Eat a salad every day with strawberries, capers, olives and dried parsley. Thank me later.
Spinach in my case v
Don't! You will live forever if you do
@@cliffmode2000 Great for magnesium but a little low in Quercetin. You can mix in alot of stuff ofcourse. One thing I forgot is pumpkin seeds. Since spermidine enhances autophagy.
More like it should be mostly parsley like an Iranian tabouleh salad to get that apigenin action. Or put parsley on every meal 😂
Don't mind me i'm gonna eat 1.5 kg of stawberrries to get my preffered ammount of fisetin.
So why not inclusion or discussion of research on cistanche and immune senolytics?
Thank you for super interesting videos 😁👍 PS.... A super simple (and free) biological clock test everyone can take, is a hearing test. (there is several free phone apps available) it's not as precise as Horvat clock, but it is an interesting "HearWhat" clock 😉
Shall we eat Quercetin now?
I feel like we should be paying for this. You should look into Patreon.
I do!
@@TheSheekeyScienceShow Oh, sweet. I didn't see it in the description.
So nothing new on safety or efficiency?
Like in the meme: "Why not both?"
Are you still taking NMN? if so, do you think it will actually have an effect on your health/life span?
I was taking NMN, but I decided to stop. It seems like our knowledge is too uncertain right now. I'm young enough that I can wait some years to see what better research will find.
Dr Brad stienfield just made a devastating video about resveratrol and pterstillene.
It would be nice to see others respond to that video. I always learn more from issues when they are debated. I like to hear multiple arguments because different people will point to different evidence. Dr. Brad Stanfield makes some good material, but sometimes he can seem too selective in what he includes and excludes.
@@MarmaladeINFP there was a person who works in the same field calling the " why I stopped taking resveratrol" video - horse manure..
