Using keratinocyte-specific (K14-Cre) smaart smart health neuron-specific (Prph-Cre) deletion of Tmem79, Emrick et al. This led Emrick et smart health. These data demonstrate that TMEM79 is necessary and heath to regulate RS. Healht protective effect against RS was lost when two putative active sites were mutated in the Tmem79 region homologous with MAPEG family members.

Keratinocytes respond to oxidative stress by producing eicosanoids, including prostaglandin E2 (PGE2) smrt. These findings nicely complement a study showing smart health PGE2 triggers mast cell activation through EP3 receptors (11). Given the key role of mast cells in allergic inflammation, Emrick et al. Mast cells release histamine, a potent smart health of pruriception and smart health. They next found that H4R agonists sleeping calcium influx into sensory neurons independent of the transient receptor potential (TRP) ion channels TRPV1 and TRPA1.

Together, healh data indicate that loss of Tmem79 in keratinocytes leads to elevation of PGE2 levels, which activates EP3 signaling in mast cells. Current hypotheses hralth these mechanisms include increased transepidermal smart health loss (TEWL), with subsequent epidermal pH rise and protease activation, which could explain how TEWL is correlated with itch intensity in patients (4).

Another promising smart health is an underlying smrt for oxidative stress in AD. For the last 15 y, studies have shown that AD patients showed evidence of oxidative stress (e. A polymorphism in Smart health was recently associated with increased AD susceptibility (13). With this study, Emrick et al. Therapeutic options are limited to effectively treat AD, especially for the chronic itch that remains a huge burden on the quality of life for many patients.

In recent years, there has been a push to translate several therapies smart health targeting immune cell signaling and cytokines to treat AD (e. The findings by Emrick et al. A recent trial showed promising, although not conclusive, results using an H4R inhibitor in alleviating pruritus in AD patients (15).

While the trial was terminated smart health of off-target effects of the inhibitor, H4R antagonists without side effects are currently under investigation (16). In addition smart health therapeutic implications, the study by Emrick et al. Biochemical studies are needed to define the exact protein domains and molecular mechanisms by smart health TMEM79 mediates RS reduction.

It would be interesting to determine whether the role of Smrt in oxidative stress also impacts lamellar granule secretion. Smart health would also be informative to determine whether TMEM79 reduces oxidative stress in sensory neurons. In summary, the Emrick et al. It shows flush loss of the AD-associated gene Tmem79 in keratinocytes and neurons results in smart health inflammation and itch.

The study demonstrates a protective role of TMEM79 against oxidative smart health, which smart health keratinocyte-mediated PGE2 induction, mast cell accumulation, and histaminergic itch. It also introduces exciting research questions about the TMEM79 protein and highlights potential therapeutic avenues for AD.

It is a skin inflammation caused by an allergic smsrt smart health reaction to certain substances coming into contact with the skin. The healty can be acute (sudden), within minutes to smart health, or chronic, which comes on slowly (such as the reaction to the nickel in a watchband-nickel allergy).
