How to activateITS has set up one Key Management Server (KMS) in Pullman to complete volume activation which is available to all WSU campuses. Select Microsoft products are configured by default to look for this service and it should be automatic. Generally, departments do not need to do anything to activate products. However, ITS may contact departments to open ports or modify firewall setting if necessary. This will be on a case-by-case basis.
KMS activation will not impact any existing installations and will only affect new and un-activated ones. Departments can block access via a firewall if departments do not want automatic activation. If a standard Multiple Activation Key (MAK) key is installed, the system will ignore the KMS. For users in remote locations or users who are not in the network, MAK will be distributed on case by case basis.

Leptin induces both in vivo eosinophil migration and activation in sensitized BALB/c mice.(A, B) show, respectively, brief schematic representations of pleurisy models induced by i.pl. injection of leptin in naïve [data shown in (C)] and sensitized [data shown in (D)] BALB/c mice employed in this study. In (C), naïve BALB/c mice received i.pl. injection with different concentrations of leptin (0.5, 1 and 2 mg/kg) and pleural fluids were collected within 24 h. In (D), sensitized BALB/c mice received i.pl. injection of leptin (1 mg/kg) and pleural fluids were collected within 6 or 24 h, as indicated. Analyses include pleural eosinophil counts evaluated in cells stained by May-Grünwald-Giemsa (upper panels), numbers of cytoplasmic lipid bodies counted within osmium-stained pleural eosinophils (middle panels) and cysLTs levels found in cell-free pleural fluids measured by specific EIA kit (bottom panels).

Resident mast cells are leptin targets and are responsible for in vivo leptin-induced eosinophil migration and activation. In (A), sensitized BALB/c mice were pre-treated with degranulating mast cell agent compound 48/80 and stimulated with leptin (1 mg/kg; i.pl.). Pleural fluids were collected after 24 h of leptin stimulation. Analyses include pleural eosinophil counts evaluated in cells stained by May-Grünwald-Giemsa (upper panels), PGD2 levels found in cell-free pleural fluids measured by specific EIA kit (middle panels) and numbers of cytoplasmic lipid bodies counted within osmium-stained pleural eosinophils (bottom panels).

Among very few other specific stimuli (21), PGD2 and CCL5 are known to directly promote activation of de novo formation of lipid bodies and LTC4 synthesis by eosinophils both in vitro and in vivo (28, 47). Here, several of our findings confirm that leptin-induced eosinophil activation in vivo appears to be dependent on mast cell-derived PGD2-driven paracrine activity in sensitized BALB/c mice, since (i) increased PGD2 levels detected as early as 6 h (Figure 3B) of leptin administration are kept elevated for at least 24 h in eosinophilic inflammatory site of leptin-challenged sensitized BALB/c; (ii) pretreatment with compound 48/80 reduced in vivo leptin-induced production of PGD2 (Figure 4A) in sensitized BALB/c mice; (iii) mast cell degranulating agent compound 48/80 blocked leptin-induced assembly of new cytoplasmic lipid bodies within recruited eosinophils as detected 24 h after leptin stimulation of sensitized BALB/c mice (Figure 4A); and, more significantly, (iv) specific inhibition of PGD2 synthesis by HQL-79 disrupted both biogenesis of cytoplasmic lipid bodies and LTC4 synthesis within recruited eosinophils in leptin-stimulated sensitized BALB/c mice (Figures 6A, C).
Leptin-induced in vivo eosinophil activation in sensitized BALB/c mice is mediated by PGD2 and CCL5. Sensitized BALB/c mice received i.pl. injection of leptin (1 mg/kg) and pleural fluids were collected within 24 h of stimulation. While in (A), animals were pre-treated with HQL-79 (1 mg/kg, i.p.), in (B) mice were pre-treated with a neutralizing anti-CCL5 antibody (10 µg/cavity, i.pl.). Analyses include numbers of cytoplasmic lipid bodies counted within osmium-stained pleural eosinophils (upper panels) and cysLTs levels found in cell-free pleural fluids measured by specific EIA kit (bottom panels). (C) shows representative images of osmium-stained pleural cells recovered from leptin-stimulated sensitized BALB/c mice which were pre-treated or not (as indicated) with HQL-79.

Here, we demonstrated the capability of leptin in triggering eosinophilic inflammation in vivo in naïve C57BL/6 or BALB/c mice. Interestingly, the leptin induced eosinophil migration was more prominent in sensitized BALB/c mice. In addition, leptin was successful in triggering activation of the infiltrating eosinophils only in pre-sensitized BALB/c mice. Evaluation of these two mouse backgrounds are currently of key relevance; inasmuch as recent reports employing BALB/c mice have defied the paradigm derived from C57BL/6 studies that eosinophils are absent from obese adipose tissue, while revealed even far-reaching protective functions of adipose tissue eosinophils (18, 48).
According to the study by Lee and coworkers (18), rather than the size of eosinophil population within adipose niche, the profile of eosinophil activation emerges as the central element of tissue function. Overall, these authors reported that, even though eosinophils accumulate in adipose tissue of obese BALB/c mice, they display homeostatic functions as proposed for the lean adipose tissue (18). Therefore, evaluating in vivo eosinophil activation, instead of the exclusive assessment of their migration pattern, was germane here. So far, the acknowledged mechanism of eosinophil homeostatic roles lays essentially on activation of eosinophil secretory activity of immune-modulator proteins, mostly cytokines like IL-4 and IL-13 (48, 51, 52). However, eosinophils have a much diverse secretory capability, which is not limited to cytokine secretion, but eosinophils are remarkable sources of multifunctional lipid mediators. Within physiologically stimulated eosinophils, bioactive lipids from arachidonic acid metabolism are synthesized primarily in cytoplasmic lipid bodies (53, 54). Of note, cytoplasmic lipid body numbers are characteristically increased within eosinophils following in vitro stimulation, as well as in in vivo inflammatory disorders, and are used as a marker of eosinophil activation (55). Besides the previously reported direct activation of lipid body biogenesis in vitro within eosinophils by leptin (16), we demonstrated that leptin administration in sensitized BALB/c mice promotes formation of new lipid bodies within the eosinophils recruited to the leptin ability to evoke eosinophil activation in vivo.
The assembly of these highly active organelles within eosinophils is often linked to intense synthesis of eicosanoids, notably LTC4, which was produced upon in vivo stimulation with leptin. LTC4 may drive adipose homeostasis since it (i) potentiates IL-5 release from ILC2s (56) and (ii) elicits IL-4 secretion from eosinophils (57). Noteworthy, we have recently demonstrated that leptin prompts LTC4 synthesis within the newly formed cytoplasmic lipid bodies in human and mouse eosinophils in vitro (16). Besides LTC4, increased leptin levels triggered by adipose tissue dysfunction, may also unbalance eosinophil lipid body-compartmentalized synthesis of other eicosanoids known to interfere with adipogenesis and inflammation (58, 59), such as the prostanoids PGE2 and PGD2 (16). Eosinophil lipid bodies are highly active intracellular sites of eicosanoid synthesis (54, 55) and may have important roles, not only in the adipose tissue physiology, but also in metabolic disease states, therefore indicating that further studies on the potential impacts of activation of eosinophilic lipid bodies on adipose tissue are germane.
Considering both leptin receptor expression by eosinophils (13) and in vitro leptin capability to activate eosinophils (14), one could assume that in vivo leptin-induced eosinophil activation described here is a consequence of direct stimulation of leptin receptors on eosinophil surface. Without precluding a partial direct effect of leptin onto eosinophils in the overall leptin-driven eosinophilic response in vivo described here, as eosinophils are not resident cells within the pleural cavity and, therefore, absent at the moment of leptin administration; leptin ability to induce in vivo eosinophil activation may mostly depend on indirect components. Among the various resident cellular targets for leptin stimulation in vivo, we identified mast cells as a key cell population. Importantly, our results identify mast cells as modulators of leptin-driven eosinophilic reaction are in line with recent postulations that adipose tissue resident mast cells or the obesity-related increased mast cell population are modulators of adipose tissue homeostasis and inflammation (60, 61).
