Background

Tyrosine-protein Kinase Mer, also known as c-Mer and MerTK, is a member of the receptor tyrosine kinase subfamily TAM (Tyro3, Axl, and Mer). Similar to Axl and Tyro3, the extracelluar domain of Mer contains two Ig-like motifs and two fibronectin type III motifs. Mer is not expressed in normal B- and T-cells but expressed in neoplastic B- and T-cell lines . It is also show higher expression in immunosuppressive M2like macrophages. Following activation by ligand, interacts with GRB2 or PLCG2 and induces phosphorylation of MAPK1, MAPK2, FAK/PTK2 or RAC1. MERTK signaling plays a role in various processes such as macrophage clearance of apoptotic cells, platelet aggregation, cytoskeleton reorganization and engulfment. Functions in the retinal pigment epithelium (RPE) as a regulator of rod outer segments fragments phagocytosis. Plays also an important role in inhibition of Toll-like receptors (TLRs)-mediated innate immune response by activating STAT1, which selectively induces production of suppressors of cytokine signaling SOCS1 and SOCS3.Mer is known to bind Gas6, Protein S, Tubby, Tubby-like protein 1 (Tulp1), and Galectin-3. Upon binding ligands via the Ig-like motif, Mer is dimerized to trans-autophosphorylate the kinase domain to induce downstream signaling. It has been shown that Mer signaling in macrophages induces M2 polarization, which promote tumor growth, metastasis and evasion of anti-tumor immunity in tumor microenviroment. Inhibition of Mer, especially on leukocytes and macrophages, is an effective anti-cancer therapy.

Kid Friendly Sensitive Mineral Sunscreen – Vegan and FSA Eligible (2026)!
Size: 0.5 Ounce (Pack of 1), Set name: Stick - 0.5 oz., Size: 0.5 Ounce (Pack of 1), Set name: Stick - 0.5 oz.
Kid friendly mineral sunscreen! I used this last year and repurchased it this year in the travel size for my toddler as she likes to apply sunscreen herself. The travel size is super easy and goes on well. Also does not make a huge mess when my toddler applies it herself. As you can see in the video, it doesn’t leave a very noticeable white cast, which is helpful when you have tan skin. Can easily reapply and not a hassle for a busy toddler. No sensitivity or rash after applying. It’s made for sensitive skin. I highly recommend for anyone who is looking for a good sunscreen for toddlers.

Best formula for Suntan Lotion.
Size: 5 Fl Oz (Pack of 1), Set name: Tube - 5 oz.
I had this in regular formula and didn’t like it. The childrens one I love! Believe me, you need sunscreen, you’ll be glad you did as your sun loving girl friends wrinkle up and look older for not using it. It looks good on, not a white cast, not oily shining, or other awful things other sunlotion does. Doesn’t stink, actually makes your face look better as gives a better lighting to wrinkles (oddly, but woman have used mineral for generations for that very reason.) kids won’t skirm away, because it does sting.

WORKS. Goes on well
Size: 0.5 Ounce (Pack of 1), Set name: Stick - 0.5 oz.
I bought this in the face stick, the regular cream, and the lip spf stick (ONLY one I could find without all the poison stuff in it). I am loving this brand! Not super white (it has to be somewhat if you want it to work without all the chemicals in it) and stays well. My kids didn’t burn at all with this on our recent trip to the beach and pool. It’s worth it.
