Background : Multi-atlas segmentation is a powerful method for automatic structural segmentation of several sub-structures in many organs. However, no study has used this method so far for skeletal muscle segmentation. In this study, we present a fully automatic multi-atlas segmentation pipeline we have developed for segmentation of quadriceps muscles from magnetic resonance images obtained in twenty five young healthy males.Materials and Methods: A non-linear registration process based on ANTs algorithm was applied to thigh images initially automatically segmented for bone, muscle and fat tissues. Optimized fusion parameters of STEPS multi-atlas segmentation were determined to obtain the highest DICE index as compared to the manual segmentation of quadriceps muscles, considered as the gold standard. Validation and reproducibility of the pipeline was assessed on two other databases of seven healthy male subjects.Results: Results for each quadriceps muscle show a mean DICE similarity coefficient higher than 0.85.Conclusion:Through some examples, we show the robustness of this registration method for the longitudinal follow-up of atypical healthy subjects and dytrophic patients.
The typical paradigm is that new technologies in medicine transition from the laboratory (Bench) through several steps towards eventual use to treat patients (Bedside). But clinical and genetic studies have a lot to teach us about dysferlinopathy and can inform research projects looking for new treatments. This webinar included overviews of the clinical phenotype and genetics of dysferlinopathy, and also highlighted some of the findings of recent clinical studies, in particular the Clinical Outcome Study in Dysferlinopathy (COS), as well as large-scale sequencing studies that document the spectrum of mutations of the DYSF gene and carry implications about the role of the dysferlin protein in muscle biology.
Recent discoveries show how dysferlin deficiency affects cellular metabolism and how diet and exercise may affect the course of dysferlinopathy. Metabolic changes in skeletal muscle are a hallmark of several types of muscular dystrophy. In vitro and in vivo studies of dysferlinopathy have identified metabolic effects are often distinct or at odds with observations from other types of muscular dystrophy. This indicates that some metabolic changes may be unique to dysferlin deficiency rather than being caused by generic dystrophic processes. This webinar included findings from metabolic studies on dysferlin-deficient muscle fibers, and the impact of dietary interventions on the phenotype of dysferlinopathy.
This webinar covered a variety of recent results across several topics related to dysferlin and dysferlinopathy – from research tools to big data analysis, to the latest insights on protein structure, to therapeutic strategies. Several laboratories presented findings that the Jain Foundation had been following with great interest, but which were not published yet. We felt that sharing these results through this webinar (which can be thought of akin to a “late breaking developments” session at a scientific conference) would be extremely valuable to the entire dysferlin research community.

Destructive Muscle Inflammation: Are Proliferating Macrophages the Culprit in Dysferlinopathy?
Vicki R Kelley1, Jea-Hyun Baek1

Macrophages (Mø) are prominent in skeletal muscles in patients with dysferlinopathy. Mø exert diverse functions; integral in both tissue repair and destruction. We initially tested the hypothesis that Mø are defective in shifting from M1-like “inflammatory/destructive” to the M2-like “reparative/regulatory” phenotype in advancing dysferlinopathy. Our preliminary data indicates that in dysferlin-deficient B6.A-Dysfprmd/GeneJ (BLA/J) mice with advancing dysferlinopathy: (1) Mø are skewed towards M1-like (express TNF-a and iNOS), compared to the M2-like (express TGF-b, IL-10 and Arginase) phenotype; (2) Mø comprise the vast majority of proliferating cells; (3) proliferating intra-muscle Mø robustly expressing TNF-a and iNOS, rather than TGF-b, IL-10 and Arginase; and (4) proliferating Mø are adjacent to necrotic muscle fibers. These findings are in stark contrast to the abundance of proliferating M2-like, not M1-like, Mø adjacent to necrotic muscle fibers during repair. We hypothesize that an unchecked expansion of M1-like Mø likely drives unrelenting muscle injury that advances dysferlinopathy. Using genetic fate mapping and in vitro experiments we are determining whether the absence of dysferlin in Mø and/or muscle is responsible for promoting Mø infiltration, proliferation and skewing towards M1 that drives non-resolving, destructive muscle inflammation. Detailing the Mø-mediated mechanisms instrumental in the pathogenesis of dysferlinopathy is likely to uncover novel therapeutic strategies for this illness.

Development:
In these mice the progressive muscular dystrophy (prmd) allele from the A/J inbred strain is crossed onto the C57BL/6 genetic background. The cross was performed in the laboratory of Dr. Isabelle Richard at Genethon and the backcross generation reached N8. In collaboration with the Jain Foundation, Dr. Richard donated the strain to The Jackson Laboratory in 2010. Upon arrival, mice were bred to C57BL/6J for at least 2 generations to establish the colony.
Mutation:
An ETn retrotransposon (5-6kb) is inserted in intron 4 of the dysferlin gene.
Symptoms:
Disease onset is observed by 2 months and is characterized by the presence of centronucleated fibers and areas of inflammation. As seen with the original background A/J, mice homozygous for the prmd allele on the C57BL/6J background display an increasing number of centronucleated fibers and impairment in the majority of muscles by 4 months of age. In order of severity, the most affected muscles are psoas, quadriceps femoris, tibialis anterior, and gastrocnemius. Mice exhibit a decreased membrane repair capacity following laser wounding experiments. In an open space assay, mice cover less distance and are less active than wild-type. Mice that are homozygous for this allele are viable, fertile and normal in size.
Comparison with other disease strains:
Disease progression is similar to A/J: slightly slower than in SJL/J, Dysf-/- (Campbell), Dysf-/- (Brown), and C57BL/10.SJL mice. As in both SJL/J and Dysf-/- (Brown) mice, proximal muscles are more severely affected than distal muscles. As in Dysf-/- (Brown) mice, abdominal muscles are also affected.
Control strain(s):
C57BL/6 (for homozygotes); littermates (for heterozygotes).

Summary: A number of findings have come to our attention at the Jain Foundation highlighting a connection between dysferlin and lipid storage, transport, and metabolism. These observations include recent publications as well as unpublished results from current research projects, involving a wide range of different observations. We feel these data, taken together, are telling us something important about dysferlin’s role in muscle health—but we aren’t sure what that is. For this reason, we think it’s important for the research community to see and discuss the recent results on dysferlin and lipids and generate hypotheses and ideas for future studies. We had planned a session devoted to this topic in the Dysferlin Conference that was scheduled to take place in March 2020. Due to the in-person conference’s postponement caused by the COVID pandemic, we decided to hold a webinar over two days, featuring findings from several labs on the dysferlin/lipid connection, with time for the community to discuss the observations and their implications.
Summary: Cells typically maintain very low levels of intracellular calcium, as it is used for a variety of signaling and proteolytic functions. For muscle fibers, however, a large calcium release from the endoplasmic reticulum initiates contraction, necessitating specialized calcium-handling adaptations in muscle. There is increasing evidence that dysferlin is part of muscle fibers’ calcium management system, as studies from different laboratories have shown that muscle’s calcium handling is altered in dysferlin’s absence. Dysferlin is known to bind calcium via its C2 domains and changes its behavior in terms of binding to lipids, to itself, and to other proteins at elevated calcium concentration. This was noted in the context of dysferlin’s role in membrane repair, where an increased calcium concentration occurs due to diffusion from the cell’s exterior. Dysferlin’s role in regulating calcium, however, appears to be broader, and extend to managing intracellular calcium during contraction. This webinar presents recent work from several research groups which offers clues to dysferlin’s role in managing calcium, and the effect on muscle fibers’ calcium handling when dysferlin in absent.
