Abstract
BACKGROUND Corneal alkali burns can lead to ulceration, perforation, and even corneal blindness due to epithelial defects and extensive cell necrosis, resulting in poor healing outcomes. Previous studies have found that chitosan-based in situ hydrogel loaded with limbal epithelium stem cells (LESCs) has a certain reparative effect on corneal alkali burns. However, the inconsistent pore sizes of the carriers and low cell loading rates have resulted in suboptimal repair outcomes. In this study, 4D bioprinting technology was used to prepare a chitosan-based thermosensitive gel carrier (4D-CTH) with uniform pore size and adjustable shape to improve the transfer capacity of LESCs. METHODS Prepare solutions of chitosan acetate, carboxymethyl chitosan, and β-glycerophosphate sodium at specific concentrations, and mix them in certain proportions to create a pore-size uniform scaffold using 4D bioprinting technology. Extract and culture rat LESCs (rLESCs) in vitro, perform immunofluorescence experiments to observe the positivity rate of deltaNp63 cells for cell identification. Conduct a series of experiments to validate the cell compatibility of 4D-CTH, including CCK-8 assay to assess cell toxicity, scratch assay to evaluate the effect of 4D-CTH on rLESCs migration, and Calcein-AM/PI cell staining experiment to examine the impact of 4D-CTH on rLESCs proliferation and morphology. Establish a severe alkali burn model in rat corneas, transplant rLESCs onto the injured cornea using 4D-CTH, periodically observe corneal opacity and neovascularization using a slit lamp, and evaluate epithelial healing by fluorescein sodium staining. Assess the therapeutic effect 4D-CTH-loaded rLESCs on corneal alkali burn through histological evaluation of corneal tissue paraffin sections stained with hematoxylin and eosin, as well as immunofluorescence staining of frozen sections. RESULTS Using the 4D-CTH, rLESCs were transferred to the alkali burn wounds of rats. Compared with the traditional treatment group (chitosan in situ hydrogel encapsulating rLESCs), the 4D-CTH-rLESC group had significantly higher repair efficiency of corneal injury, such as lower corneal opacity score (1.2 ± 0.4472 vs 0.4 ± 0.5477, p < 0.05) and neovascularization score (5.5 ± 1.118 vs 2.6 ± 0.9618, p < 0.01), and significantly higher corneal epithelial wound healing rate (72.09 ± 3.568% vs 86.60 ± 5.004%, p < 0.01). CONCLUSION In summary, the corneas of the 4D-CTH-rLESC treatment group were similar to the normal corneas and had a complete corneal structure. These findings suggested that LESCs encapsulated by 4D-CTH significantly accelerated corneal wound healing after alkali burn and can be considered as a rapid and effective method for treating epithelial defects.

Ocular injury progression and cornea histopathology from chloropicrin vapor exposure: Relevant clinical biomarkers in mice. Exp Eye Res 2023; 230:109440. [PMID: 36933694 DOI: 10.1016/j.exer.2023.109440] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 03/13/2023] [Accepted: 03/16/2023] [Indexed: 03/18/2023]
Abstract
Ocular tissue is highly sensitive to chemical exposures. Chloropicrin (CP), a choking agent employed during World War I and currently a popular pesticide and fumigating agent, is a potential chemical threat agent. Accidental, occupational, or intentional exposure to CP results in severe ocular injury, especially to the cornea; however, studies on ocular injury progression and underlying mechanisms in a relevant in vivo animal model are lacking. This has impaired the development of effective therapies to treat the acute and long-term ocular toxicity of CP. To study the in vivo clinical and biological effects of CP ocular exposure, we tested different CP exposure doses and durations in mice. These exposures will aid in the study of acute ocular injury and its progression as well as identify a moderate dose to develop a relevant rodent ocular injury model with CP. The left eyes of male BALB/c mice were exposed to CP (20% CP for 0.5 or 1 min or 10% CP for 1 min) using a vapor cap, with the right eyes serving as controls. Injury progression was evaluated for 25 days post-exposure. CP-exposure caused a significant corneal ulceration and eyelid swelling which resolved by day 14 post exposure. In addition, CP-exposure caused significant corneal opacity and neovascularization. Development of hydrops (severe corneal edema with corneal bullae) and hyphema (blood accumulation in the anterior chamber) was observed as advanced CP effects. Mice were euthanized at day 25 post-CP-exposure, and the eyes were harvested to further study the corneal injury. Histopathological analyses showed a significant CP-induced decrease in corneal epithelial thickness and increased stromal thickness with more pronounced damage, including stromal fibrosis, edema, neovascularization, trapped epithelial cells, anterior and posterior synechiae, and infiltration of inflammatory cells. Loss of the corneal endothelial cells and Descemet's membrane could be associated with the CP-induced corneal edema and hydrops which could lead to long term term pathological conditions. Although exposure to 20% CP for 1 min caused more eyelid swelling, ulceration, and hyphema, similar effects were observed with all CP exposures. These novel findings following CP ocular exposure in a mouse model outline the corneal histopathologic changes that associate with the continuing ocular clinical effects. The data are useful in designing further studies to identify and correlate the clinical and biological markers of CP ocular injury progression with acute and long-term toxic effects on cornea and other ocular tissues. We take a crucial step towards CP ocular injury model development and in pathophysiological studies to identify molecular targets for therapeutic interventions.

Abstract
The possibility of using drug loaded bovine serum albumin (BSA) porous films as therapeutic contact lenses is investigated. Kaempferol (KAE), a hydrophobic antioxidant and anti-inflammatory agent, is incorporated into BSA porous films to form BSA/KAE films. The BSA/KAE films are transparent in the visible wavelength range of the human eye, possessing high water content and good cytocompatibility. A prolonged and sustained drug release is observed, and the in vivo efficacy of BSA/KAE films is better than the individual KAE. BSA/KAE films promoted the corneal re-epithelialization, inhibited neovascularization, and reduced the inflammation of an alkali burn induced corneal injury model. The study demonstrates the promising potential of BSA/KAE films as therapeutic contact lenses for the treatment of corneal injury, builds an available ocular drug delivery platform for ocular diseases.

Abstract
FK506-binding proteins (FKBPs) belong to the immunophilin family and are linked to various disease states, including the inflammatory response. The inhibition of cytokine and chemokine expression in addition to positive effects of FKBPs on corneal inflammation in animal models suggests that they may be used for ophthalmic delivery in the treatment of dry eye disease. To pass the effective barriers protecting eye tissues, testing the transduction domains of FKBPs is essential. However, monitoring their transduction efficiencies is not a simple task. The quantitative measurement of FKBP interactions was performed using a cell model with a specific G protein-coupled receptor, as FKBPs had been known to act at the inositol 1,4,5-trisphosphate receptor (IP3R) leading to the inhibition of intracellular calcium mobilization. Because of its luminescence amplitude and stability, human urotensin II receptor was expressed in aequorin parental cells to measure the action of selected FKBPs. This luminescence-based functional assay platform exhibited a high signal-to-background ratio of more than 100 and a Z' factor at 0.6204. As expected, changes in the sequence of the transduction domain affected the function of the FKBPs. The intracellular calcium mobilization assay with selected FKBPs represented a robust and reliable platform to screen initial candidates. Although the precise nature of the control that FKBPs exert on the IP3R is uncertain, this approach can be used to develop innovative anti-inflammatory treatments for dry eye disease by optimizing protein transduction domain sequences.

Abstract
Hyaluronic acid (HA) was covalently linked to the surface of bovine serum albumin/silver (BSA/Ag) porous films to fabricate a possible contact lens. The BSA/Ag/HA films showed favorable properties as contact lenses, including acceptable transparency, high water content, good hemocompatibility, non-cytotoxicity and antibacterial properties. The therapeutic potential of the BSA/Ag/HA films was evaluated on an alkali burn-induced corneal injury model on mice. The corneal healing rate was enhanced, the corneal opacification and neovascularization were lessened, and the inflammation response was reduced. The chemical cross-linking of HA on the films prolonged the retention time of HA on the corneal surface, thus enhanced the drug efficacy and improved the patient compliance, proving the high potential of BSA/Ag/HA films as contact lenses.

Abstract
The aim of this study was to investigate the effect of mesenchymal stem cells (MSCs) on the angiogenesis of human umbilical vein endothelial cells (HUVECs). MSCs were subconjunctival injected into rat corneal alkali burn models. Their impacts on the degree of corneal neovascularization (CNV) and corneal opacity were evaluated at 3, 6, 9 and 12 days after injection. An in vitro experiment of MSCs affecting HUVECs angiogenesis was performed and evaluated using the tube formation assay. The results showed that both CNV and corneal opacity were decreased in rats after MSCs injection. In HUVECs, angiogenesis of cells was inhibited by miR-211 overexpression. miR-211 negatively regulated Prox1 expression. Knockdown of miR-211 blocked the decrease of Prox1 expression induced by MSCs and the inhibitory effect of MSCs on the angiogenesis of HUVECs. The critical role of miR-211 in MSCs inhibition of corneal angiogenesis was confirmed in rat experiments. We concluded that MSCs inhibited the angiogenesis of HUVEC through miR-211 mediating the down-regulation of Prox1.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Adenophora triphylla var. japonica is frequently used as an oriental medicinal plant in Korea, China, and Japan for its anti-inflammatory, antitussive, and hepatoprotective effects. AIM OF THE STUDY In the present study, the antitussive, expectorant, and anti-inflammatory effects of AR powder were investigated using animal models to evaluate their potential to treat respiratory disorders. MATERIALS AND METHODS AR powder was administered orally to mice once daily for 11 days, at dose levels of 400, 200, and 100 mg/kg. Theobromine (TB), ambroxol (AM) and dexamethasone (DEXA) were used as standard drugs for antitussive effects, expectorant effects and anti-inflammatory effects, respectively. Evaluations of antitussive effects were based on changes in body weight, the number of cough responses and the histopathology of the lung and trachea. Expectorant effects were based on changes in the body weight, macroscopic observations of body surface redness, the mucous secretion of the trachea and histopathology of lung (secondary bronchus). Anti-inflammatory effects were based on changes in the body weight, macroscopic observations involving redness and edema of the treated ear, absolute and relative ear weights and histopathology of the treated ears. RESULTS Allergic acute inflammation and coughing induced by exposure to NH4OH and symptoms of xylene-induced contact dermatitis were significantly inhibited by treatment with AR powder in a dose-dependent manner. Histological analyses revealed that AR powder decreased the OD values in trachea lavage fluid, reduced body surface redness, thicknesses of intrapulmonary secondary bronchus mucosa, and the number of PAS-positive mucous producing cells. Overall, AR powder administered at 200 mg/kg displayed superior antitussive and expectorant effects as compared to TB (50 mg/kg), and AM (250 mg/kg). At the highest concentration (400 mg/kg) AR powder displayed only moderately improved anti-inflammatory activities as compared to DEXA (1 mg/kg). CONCLUSION The results obtained in this study suggest that AR powder exerts dose-dependent, favorable antitussive, expectorant, and anti-inflammatory activities achieved through modulation of the activity of mast cells and respiratory mucous production. Therefore, AR powder may serve as a therapeutic agent in various respiratory disorders, especially those that occur as a result of environmental toxicants.

Abstract
Expression of hypoxia-inducible factor (HIF) 1α has been observed in corneal neovascularization (CNV). Vascular endothelial growth factor (VEGF), one of the most well-known angiogenic factors in CNV, is under the regulation of HIF-1. The present study aims to investigate the synergistic effects of VEGF and HIF-1α gene silencing on alkali burn-induced CNV in rabbits. The models of rabbits in corneal alkali burn were established. SiRNA recombinant adenovirus was used to explore the synergistic effects of VEGF and HIF-1α gene silencing on alkali burn-induced CNV. CNV area and ultrastructure of cornea were observed. The expression of VEGF and HIF-1α was detected. CNV was observed in rabbits following alkali burn. In addition, overexpressed VEGF and HIF-1α was also observed in rabbits following alkali burn. Then, silencing HIF-1α or silencing VEGF decreased area of CNV, inhibited neovascularization and improved pathological changes, while double-target interference for VEGF and HIF-1α decreased area of CNV inhibited neovascularization, and improved pathological changes to a greater extent. Our study provides evidences emphasizing the distinct notion that VEGF and HIF-1α play the contributory role in alkali burn-induced CNV as a result of double-target interference for VEGF and HIF-1α inhibiting CNV in rabbits following corneal alkali burn.

Abstract
Shiunko ointment is composed of five ingredients including Lithospermi Radix (LR), Angelicae Gigantis Radix, sesame seed oil, beeswax, and swine oil. It is externally applied as a treatment for a wide range of skin conditions such as eczema, psoriasis, hair loss, burns, topical wounds, and atopic dermatitis. Deoxyshikonin is the major angiogenic compound extracted from LR. In this study, we investigated the efficacy of LR extract and deoxyshikonin on impaired wound healing in streptozotocin (STZ)-induced diabetic mice. Treatment with LR extract elevated tube formation in human umbilical vein endothelial cells (HUVECs) and exerted antioxidant activity. An open skin wound was produced on the backs of diabetic mice and was then topically treated with deoxyshikonin or vehicle. In addition, deoxyshikonin promoted tube formation in high glucose conditions exposed to HUVECs, and which may be regulated by increased VEGFR2 expression and phosphorylation of Akt and p38. Our results demonstrate that deoxyshikonin application promoted wound repair in STZ-induced diabetic mice. Collectively, these data suggest that deoxyshikonin is an active ingredient of LR, thereby contributing to wound healing in patients with diabetes.

Tetramethylpyrazine (TMP) ameliorates corneal neovascularization via regulating cell infiltration into cornea after alkali burn. Biomed Pharmacother 2018; 109:1041-1051. [PMID: 30551354 DOI: 10.1016/j.biopha.2018.10.091] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2018] [Revised: 10/08/2018] [Accepted: 10/15/2018] [Indexed: 11/20/2022] Open
Abstract
In the present study, we investigated the underlying mechanism of tetramethylpyrazine (TMP)-medicated inhibition of corneal neovascularization (CNV). Our data showed that TMP could effectively downregulate the expression levels of CXCR4 mRNA and protein, as well as inhibit HUVECs, endothelial cells, tubule formation in vitro. In vivo, alkali burn (1 M NaOH) could remarkably upregulate CXCR4 expression and increase the migration of TNF-α-positive cells to corneal stroma. TMP drops could significantly downregulate CXCR4 expression in cornea, compared to the control. However, there was no difference in the downregulation of CXCR4 between TMP and FK506, an immunosuppressive drug. Moreover, the immunofluorescent staining of CD45 showed TMP and FK506 could significantly restrain the bone marrow (BM)-derived infiltration while the F4/80 staining reflects the suppression of macrophage aggregation. Meanwhile TMP could regulate the Interleukin 10 (IL-10) and FK506 could restrain the Interleukin 2 (IL-2). Furthermore, TMP and FK506 significantly ameliorate corneal opacity and neovascularization. Clinical assessment detected an obvious improvement in TMP and FK506 treatment groups, compared to controls in vivo. Thus, TMP had similar effects in inhibition of immune response and CNV by suppressing BM-infiltrating cells into cornea as FK506. TMP could be a potential agent in eye-drop therapy for cornea damaged by Alkali Burn.

Abstract
AIMS The alkali-induced corneal injury is an ocular emergency that required an immediate and effective management to preserve the normal corneal functions and transparency. Olopatadine is a fast, topically-effective anti-allergic drug, which exhibited potent anti-inflammatory and anti-angiogenic abilities in different allergic animals' models. Therefore, this study aimed to evaluate the therapeutic effect of olopatadine on alkali-induced corneal injury in rats. MATERIALS AND METHODS Corneal alkali injury (CI) induced in the right eyes of an eight-week-old male Wister rats, by application of 3 mm diameter filter-papers, soaked for 10 s in 1 N-NaOH, to the right eyes' corneal centers for 30 s, afterward, the filter paper removed, and the rat right eye rinsed with 20 ml normal saline. For treatment of CI, either 0.2% or 0.77% olopatadine applied topically daily for 14 days, starting immediately after the induction of CI. KEY FINDINGS Olopatadine, in the present work, effectively and dose-dependently enhanced the corneal healing after alkali application, with significant reduction of the corneal opacity and neovascularization scores, besides, it suppressed the augmented corneal IL-1β, VEGF, caspase-3 levels, and nuclear NF-κB immunohistochemical expression, meanwhile it abrogated the corneal histopathological changes, induced by alkali application. SIGNIFICANCE Olopatadine appears to be a potential treatment option for alkali-induced corneal injury.

Abstract
Despite the increasing number of effective therapeutics for eye diseases, their treatment is still challenging due to the presence of effective barriers protecting eye tissues. Cell Penetrating Peptides (CPPs), synthetic and natural short amino acid sequences able to cross cellular membrane thanks to a transduction domain, have been proposed as possible enhancing strategies for ophthalmic delivery. In this review, a general description of CPPs classes, design approaches and proposed cellular uptake mechanisms will be provided to the reader as an introduction to ocular CPPs application, together with an overview of the main problems related to ocular administration. The results obtained with CPPs for the treatment of anterior and posterior segment eye diseases will be then introduced, with a focus on non-invasive or minimally invasive administration, shifting from CPPs capability to obtain intracellular delivery to their ability to cross biological barriers. The problems related to in vitro, ex vivo and in vivo models used to investigate CPPs mediated ocular delivery will be also addressed together with potential ocular toxicity issues.

Abstract
Oxidative stress is known to be a primary risk factor for neuronal diseases. Glutaredoxin (GLRX)‑1, a redox‑regulator of the thioredoxin superfamily, is known to exhibit an important role in cell survival via various cellular functions. However, the precise roles of GLRX1 in brain ischemia are still not fully understood. The present study investigated whether transduced PEP‑1‑GLRX1 protein has protective effects against oxidative stress in cells and in an animal model. Transduced PEP‑1‑GLRX1 protein increased HT‑22 cell viability under oxidative stress and this fusion protein significantly reduced intracellular reactive oxygen species and levels of DNA damage. In addition, PEP‑1‑GLRX1 protein regulated RAC‑a serine/threonine‑protein kinase and mitogen‑activated protein kinase signaling, in addition to apoptotic signaling including B cell lymphoma (Bcl)‑2, Bcl‑2 associated X, apoptosis regulator, pro‑caspase‑9 and p53 expression levels. In an ischemic animal model, it was verified that PEP‑1‑GLRX1 transduced into the Cornu Ammonis 1 region of the animal brain, where it markedly protected against ischemic injury. These results indicate that PEP‑1‑GLRX1 attenuates neuronal cell death resulting from oxidative stress in vitro and in vivo. Therefore, PEP‑1‑GLRX1 may exhibit a beneficial role in the treatment of neuronal disorders, including ischemic injury.

Abstract
Polycystic kidney disease (PKD) is one of the most common inherited disorders, involving progressive cyst formation in the kidney that leads to renal failure. FK506 binding protein 12 (FK506BP) is an immunophilin protein that performs multiple functions, including regulation of cell signaling pathways and survival. In this study, we determined the roles of PEP-1-FK506BP on cell proliferation and cyst formation in PKD cells. Purified PEP-1-FK506BP transduced into PKD cells markedly inhibited cell proliferation. Also, PEP-1-FK506BP drastically inhibited the expression levels of p-Akt, p-p70S6K, p-mTOR, and p-ERK in PKD cells. In a 3D-culture system, PEP-1-FK506BP significantly reduced cyst formation. Furthermore, the combined effects of rapamycin and PEP-1-FK506BP on cyst formation were markedly higher than the effects of individual treatments. These results suggest that PEP-1-FK506BP delayed cyst formation and could be a new therapeutic strategy for renal cyst formation in PKD. [BMB Reports 2017; 50(9): 460-465].

Abstract
Tumor microenvironment is a complex multistep event which involves several hallmarks that transform the normal cell into cancerous cell. Designing the novel antagonistic molecule to reverse the tumor microenvironment with specific target is essential in modern biological studies. The novel 4-phenyl-2-phenoxyacetamide thiazole analogues 8a-ab were synthesized in multistep process, then screened and assessed for cytotoxic and anti-proliferative effects in vitro against multiple cancer cells of different origin such as MCF-7, A549, EAC and DLA cells which revealed that compound 8f with fluoro and methyl substitute has potential cytotoxic efficacy with an average IC50 value of ˜ 13 μM. The mechanism of cytotoxicity assessed for anti-tumor studies both in ascites and solid tumor models in-vivo inferred the regressed tumor activity. This is due to changes in the cause of tumor microenvironment with crackdown of neovascularization and evoking apoptosis process as assessed by CAM, corneal vascularization and apoptotic hallmarks in 8f treated cells. The molecular gene studies inferred involvement of HIF-1upregulation and stabilization of p53 which are interlinked in signaling as conferred by immunoblot analysis.

Abstract
Background Fermented black ginseng (FBG) is produced through several cycles of steam treatment of raw ginseng, at which point its color turns black. During this process, the original ginsenoside components of raw ginseng (e.g., Re, Rg1, Rb1, Rc, and Rb2) are altered, and less-polar ginsenosides are generated (e.g., Rg3, Rg5, Rk1, and Rh4). The aim of this study was to determine the effect of FBG on wound healing. Methods The effects of FBG on tube formation and on scratch wound healing were measured using human umbilical vein endothelial cells (HUVECs) and HaCaT cells, respectively. Protein phosphorylation of mitogen-activated protein kinase was evaluated via Western blotting. Finally, the wound-healing effects of FBG were assessed using an experimental cutaneous wounds model in mice. Results and Conclusion The results showed that FBG enhanced the tube formation in HUVECs and migration in HaCaT cells. Western blot analysis revealed that FBG stimulated the phosphorylation of p38 and extracellular signal-regulated kinase in HaCaT cells. Moreover, mice treated with 25 μg/mL of FBG exhibited faster wound closure than the control mice did in the experimental cutaneous wounds model in mice.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Resin known as Resina Pini is listed in the Korean and Japanese pharmacopoeias and has been used for treating skin wounds and inflammation. Resin is composed of more than 50% abietic acid and 10% neutral substances. OBJECTIVE In the present study, the wound-healing effects of abietic acid and the possible underlying mechanism of action were investigated in various in vitro and in vivo models. MATERIALS AND METHODS The effects of abietic acid on tube formation and migration were measured in human umbilical vein vascular endothelial cells (HUVECs). Protein expression of mitogen-activated protein kinase (MAPK) activation was evaluated via Western blotting analysis. The wound-healing effects of abietic acid were assessed using a mouse model of cutaneous wounds. RESULTS The results showed that abietic acid enhanced cell migration and tube formation in HUVECs. Abietic acid induced significant angiogenic potential, which is associated with upregulation of extracellular signal-regulated kinase (ERK) and p38 expression. Additionally, 0.8μM abietic acid-treated groups showed accelerated wound closure compared to the controls in a mouse model of cutaneous wounds. CONCLUSION The current data indicate that abietic acid treatment elevated cell migration and tube formation in HUVECs by the activation of ERK and p38 MAPKs. We suggest that abietic acid can be developed as a wound-healing agent.

Abstract
Oxidative stress is highly involved in the development of diabetes mellitus by destruction of pancreatic β-cells. DJ-1 is an antioxidant protein and DJ-1 expression levels are known to be reduced in diabetes mellitus. Thus, we examined the effects of DJ-1 protein against oxidative stress-induced pancreatic β-cell (RINm5F) death using cell permeable wild-type and mutant-type (C106A) Tat-DJ-1 proteins, which both efficiently transduced into RINm5F cells. Intracellular stability of wild-type Tat-DJ-1 persisted two times longer than C106A Tat-DJ-1. Wild-type Tat-DJ-1 protein markedly protected cells from hydrogen peroxide-induced toxicities such as cell death, reactive oxygen species generation, and DNA fragmentation. Further, wild-type Tat-DJ-1 protein significantly inhibited hydrogen peroxide-induced activation of mitogen-activated protein kinases and NF-κB signaling. On the other hand, C106A Tat-DJ-1 protein did not show the same protective effects. These results indicate that wild-type Tat-DJ-1 inhibits oxidative stress-induced cellular toxicity and activation of mitogen-activated protein kinases and NF-κB signals in RINm5F cells. These results suggest that wild-type Tat-DJ-1 protein may be a potential therapeutic agent against diabetes mellitus or toward the prevention of pancreatic β-cell destruction.
