Background

IL-12 is a heterodimeric pleiotropic cytokine made up of a 40 kDa (p40) subunit and a 35 kDa (p35) subunit.IL-12 is involved in the differentiation of naive T cells into Th1 cells. It is known as a T cell-stimulating factor, which can stimulate the growth and function of T cells. It stimulates the production of interferon-gamma (IFN-γ) and tumor necrosis factor-alpha (TNF-α) from T cells and natural killer (NK) cells, and reduces IL-4 mediated suppression of IFN-γ. T cells that produce IL-12 have a coreceptor, CD30, which is associated with IL-12 activity.IL-12 plays an important role in the activities of natural killer cells and T lymphocytes. IL-12 mediates enhancement of the cytotoxic activity of NK cells and CD8+ cytotoxic T lymphocytes. IL-12 is produced by macrophages and B cells and has been shown to have multiple effects on T cells and natural killer (NK) cells. While mouse IL-12 is active on both human and mouse cells, human IL-12 is not active on mouse cells.

Best Diaper Brand!
Size: Size 1, Unit Count: 96
Got these as a gift for my friend who just had a baby and she was thrilled! Never underestimate the simple gift of diapers to a momma with a newborn! Mother said she prefers these diapers because of their quality and softness. This is about the best price for high quality diapers you can find!

Great Product-Love These
Size: Newborn, Unit Count: 31
We have tried other name brand diapers over the years and people rave about other brands, but our experience with other brands is not good. Even the hospital doesn't use this brand and baby's onesie kept getting wet. They were folding their Pampers down at top for umbilical cord where Huggies have cut out for umbilical cord. Our personal experience is other name brand diapers seem to leak with our babies, and these stay snug and keep clothes and baby dry. When it says 100% leak proof and all-around blowout blocker it's factual for us and our babies. They are easy to use and durable. We have babies with sensitive skin and there is no irritation with these diapers.

Feat of diaper engineering
Size: Preemie, Unit Count: 30
I liked these well enough until my preemie had the biggest poo I’ve ever seen. That diaper probably weighed almost as much as he does and his white footie pajamas were untouched. Miracle. Worth every penny. Absolute legend.

Perfect thank you
Size: Newborn, Unit Count: 144
These baby diapers have been an excellent choice. They are very soft against the skin, which helps prevent irritation or chafing—even for babies with sensitive skin. Their absorbency is excellent, keeping the baby dry for several hours, both day and night. Furthermore, the fit is comfortable and secure, allowing the baby to move freely without any leaks. Without a doubt, they are practical, reliable, and provide peace of mind for parents. Highly recommended!

Outstanding, top of the line diaper!
Size: Preemie, Unit Count: 30
We normally use Huggies Little Movers with our 3.5 year old (nothing against them, they're also great diapers) but recently decided to give Swaddlers a try, and will not be going back. This is a top-of-the-line diaper and excels in all ways. We use a size 7 though could *probably* get away with a size 6, and use about 4-5 diapers a day on average (not including his overnight diaper) depending on how much he's had to drink and how often he poops -usually once a day, but could be as many as 3 times, especially if he doesn't go one day. The first thing you notice about these diapers is how soft they are. I mean, they just feel like they would be comfortable on a child, and since they're in them practically 24/7, that's important. The diaper is mostly white, and the overall designs are more muted than a lot of other diapers, with "Shilo and Friends" -an elephant and duck - on the front and back. I personally wouldn't mind something bolder, I don't think my child cares or even notices. There is a wetness indicator that goes down the length of the diaper, front and back. Nice to have I suppose for a caregiver who maybe doesn't change a lot of diapers, but at this age and stage, it's easy to know and tell. Like all Pampers diapers, they are scented. I happen to love the gentle powder-like scent, but it's a turn-off to some who describe it as too strong, and of course, if your child is sensitive to that, you may want to avoid Pampers diapers. Inside, the top sheet liner keeps his skin dry, even when he wets heavily -which is usually - and does a good job of keeping poop from sticking to his bottom. The "blowout barrier" in the back also helps contain any messes. In terms of absorbency, I'm pretty amazed at how much they can hold. Being a little older, he tends to stay drier for longer periods and then pee a larger amount at one time, but the diaper almost always holds it in, and leaks are rare. The one thing I wish that Pampers did do was have wider tapes, like Huggies, at least on the larger sizes, where kids are more active. It hasn't been a problem, so I don't really have a reason for saying that, other than that it seems like it would help with fit, but it certainly won't keep me from buying or using them in the future.
