MRI/PET multimodal imaging of the innate immune response in skeletal muscle and draining lymph node post vaccination in rats. Front Immunol 2023; 13:1081156. [PMID: 36713458 PMCID: PMC9874296 DOI: 10.3389/fimmu.2022.1081156] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Accepted: 12/23/2022] [Indexed: 01/13/2023] Open
Abstract
The goal of this study was to utilize a multimodal magnetic resonance imaging (MRI) and positron emission tomography (PET) imaging approach to assess the local innate immune response in skeletal muscle and draining lymph node following vaccination in rats using two different vaccine platforms (AS01 adjuvanted protein and lipid nanoparticle (LNP) encapsulated Self-Amplifying mRNA (SAM)). MRI and 18FDG PET imaging were performed temporally at baseline, 4, 24, 48, and 72 hr post Prime and Prime-Boost vaccination in hindlimb with Cytomegalovirus (CMV) gB and pentamer proteins formulated with AS01, LNP encapsulated CMV gB protein-encoding SAM (CMV SAM), AS01 or with LNP carrier controls. Both CMV AS01 and CMV SAM resulted in a rapid MRI and PET signal enhancement in hindlimb muscles and draining popliteal lymph node reflecting innate and possibly adaptive immune response. MRI signal enhancement and total 18FDG uptake observed in the hindlimb was greater in the CMV SAM vs CMV AS01 group (↑2.3 - 4.3-fold in AUC) and the MRI signal enhancement peak and duration were temporally shifted right in the CMV SAM group following both Prime and Prime-Boost administration. While cytokine profiles were similar among groups, there was good temporal correlation only between IL-6, IL-13, and MRI/PET endpoints. Imaging mass cytometry was performed on lymph node sections at 72 hr post Prime and Prime-Boost vaccination to characterize the innate and adaptive immune cell signatures. Cell proximity analysis indicated that each follicular dendritic cell interacted with more follicular B cells in the CMV AS01 than in the CMV SAM group, supporting the stronger humoral immune response observed in the CMV AS01 group. A strong correlation between lymph node MRI T2 value and nearest-neighbor analysis of follicular dendritic cell and follicular B cells was observed (r=0.808, P<0.01). These data suggest that spatiotemporal imaging data together with AI/ML approaches may help establish whether in vivo imaging biomarkers can predict local and systemic immune responses following vaccination.

Yu H, Luo X. The Healing Effects of Piano Practice-Induced Hand Muscle Injury. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:1020504. [PMID: 35898486 PMCID: PMC9313958 DOI: 10.1155/2022/1020504] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Revised: 06/25/2022] [Accepted: 07/01/2022] [Indexed: 11/17/2022]
Abstract
Background The muscles related to piano practice are mainly concentrated in the fingers and upper limbs, and the muscles related to other parts of the body are weak. Compared with other sports injuries, the injuries caused by piano practice are mainly chronic injuries caused by long-term strain of the upper limbs, and acute injuries rarely occur. The purpose of this study was to analyze the therapeutic effect of hand muscle injury caused by piano practice. Method A total of 60 patients with hand muscle injury caused by piano practice admitted to our hospital from January 2019 to June 2020 were selected. According to the number random grouping method, they were randomly divided into two groups. There were 30 patients in the observation group, including 20 males and 10 females, aged 24-53 (39.51 ± 7.01) years old, and the course of disease was 1-5 (3.24 ± 1.62) months. In the control group, there were 30 patients, including 18 males and 12 females, aged 24-56 (39.62 ± 7.17) years old, and the course of disease was 1.5-5 (3.14 ± 1.71) months. If the observation group experienced excessive pain, the group took ibuprofen sustained-release capsules. On weekdays, exercise your fingers 2-3 times per day. After the intervention, the wrist joint function score of the observation group was higher than that before the intervention. Results Before treatment, there was no significant difference in pain level scores between the two groups (P > 0.05). After treatment, the limb pain score in the observation group was lower than that in the control group. The effective rate of hand tendon rehabilitation in the observation group was 93.33%. The effective rate of hand tendon rehabilitation in the control group was 70.00%. The comparison results showed that there was statistical significance (P < 0.05). The score of the observation group was significantly higher than that of the control group, with statistically significant differences (P < 0.05). Conclusion Piano workouts can cause hand muscle difficulties, which can be alleviated by daily finger gymnastics. Daily finger exercises are simple and not limited by time and place. Piano practitioners can use the spare time of daily training and performance to exercise for a long time, so as to prevent or recover finger muscle damage caused by piano practice. It has the potential to help pianists avoid hand muscle injuries when practicing while also allowing music to reach its full potential.

Multiparametric magnetic resonance imaging to characterize cabotegravir long-acting formulation depot kinetics in healthy adult volunteers. Br J Clin Pharmacol 2021; 88:1655-1666.

Abstract
AIM Cabotegravir long-acting (LA) intramuscular (IM) injection is being investigated for HIV preexposure prophylaxis due to its potent antiretroviral activity and infrequent dosing requirement. A subset of healthy adult volunteers participating in a Phase I study assessing cabotegravir tissue pharmacokinetics underwent serial magnetic resonance imaging (MRI) to assess drug depot localization and kinetics following a single cabotegravir LA IM targeted injection. METHODS Eight participants (four men, four women) were administered cabotegravir LA 600 mg under ultrasonographic-guided injection targeting the gluteal muscles. MRI was performed to determine injection-site location in gluteal muscle (IM), subcutaneous (SC) adipose tissue and combined IM/SC compartments, and to quantify drug depot characteristics, including volume and surface area, on Days 1 (≤2 hours postinjection), 3 and 8. Linear regression analysis examined correlations between MRI-derived parameters and plasma cabotegravir exposure metrics, including maximum observed concentration (Cmax ) and partial area under the concentration-time curve (AUC) through Weeks 4 and 8. RESULTS Cabotegravir LA depot locations varied by participant and were identified in the IM compartment (n = 2), combined IM/SC compartments (n = 4), SC compartment (n = 1) and retroperitoneal cavity (n = 1). Although several MRI parameter and exposure metric correlations were determined, total depot surface area on Day 1 strongly correlated with plasma cabotegravir concentration at Days 3 and 8, Cmax and partial AUC through Weeks 4 and 8. CONCLUSION MRI clearly delineated cabotegravir LA injection-site location and depot kinetics in healthy adults. Although injection-site variability was observed, drug depot surface area correlated with both plasma Cmax and partial AUC independently of anatomical distribution.

Muscular Contribution to Adolescent Idiopathic Scoliosis from the Perspective of Stem Cell-Based Regenerative Medicine. Stem Cells Dev 2020; 28:1059-1077.

Abstract
Adolescent idiopathic scoliosis (AIS) is a relatively frequent disease within a range 0.5%-5.0% of population, with higher frequency in females. While a resultant spinal deformity is usually medically benign condition, it produces far going psychosocial consequences, which warrant attention. The etiology of AIS is unknown and current therapeutic approaches are symptomatic only, and frequently inconvenient or invasive. Muscular contribution to AIS is widely recognized, although it did not translate to clinical routine as yet. Muscle asymmetry has been documented by pathological examinations as well as systemic muscle disorders frequently leading to scoliosis. It has been also reported numerous genetic, metabolic and radiological alterations in patients with AIS, which are linked to muscular and neuromuscular aspects. Therefore, muscles might be considered an attractive and still insufficiently exploited therapeutic target for AIS. Stem cell-based regenerative medicine is rapidly gaining momentum based on the tremendous progress in understanding of developmental biology. It comes also with a toolbox of various stem cells such as satellite cells or mesenchymal stem cells, which could be transplanted; also, the knowledge acquired in research on regenerative medicine can be applied to manipulation of endogenous stem cells to obtain desired therapeutic goals. Importantly, paravertebral muscles are located relatively superficially; therefore, they can be an easy target for minimally invasive approaches to treatment of AIS. It comes in pair with a fast progress in image guidance, which allows for precise delivery of therapeutic agents, including stem cells to various organs such as brain, muscles, and others. Summing up, it seems that there is a link between AIS, muscles, and stem cells, which might be worth of further investigations with a long-term goal of setting foundations for eventual bench-to-bedside translation.
