Abstract
Lipofuscin aggregation may result from incomplete degradation of damaged mitochondria by autophagy-lysosome pathway, and intra-mitochondrial lipofuscin aggregation may exacerbate mitochondrial abnormalities in mitochondrial myopathy (MM) and mitochondrial disease. We examined vastus lateralis muscle biopsies from 24 patients with pathologically diagnosed MM and clinically diagnosed chronic progressive external ophthalmoplegia, in comparison to the biopsies from 3 other groups:10 patients with inclusion body myositis (IBM), 11 younger adults, and 10 older subjects with no to minimal myopathic changes. Lipofuscin aggregation in muscle fibres was assessed on autofluorescence microscopy, some histochemical stains, and electron microscopy (EM). EM analyses demonstrated intra-mitochondrial lipofuscin aggregates, spherical dense bodies (SDBs), and paracrystalline inclusions (PCIs) which were semi-quantitatively assessed. Intra-mitochondrial lipofuscin aggregates showed no significant differences between groups of MM patients and older subjects or IBM patients, but significant differences between groups of younger adults and others with associated age-related changes. Intra-mitochondrial SDBs were significantly more in MM patients than in older subjects, IBM patients, and younger adults. There was a significant positive correlation between intra-mitochondrial lipofuscin aggregates and SDBs. These findings suggest that intra-mitochondrial formation of lipofuscin SDBs is more in MM and contributing to the pathophysiology of mitochondrial disease.

Abstract
The harlequin ichthyosis (ichq) mouse mutation arose spontaneously in 1989 in a colony of BALB/cJ mice at The Jackson Laboratory. Affected mice developed thick skin due to formation of compact, orthokeratotic scales that fractured over articular surfaces, secondary to bending. Harlequin ichthyosis mice on the inbred BALB/cJ background died between 9 and 12 days of age. Onset of the clinical phenotype corresponded with emergence of hair fibers from follicles at 5 days of age. There was marked proliferation of the root sheaths of anagen hair follicles, limited to the region within the dermis. Sebaceous glands were present but small compared with those of littermate controls. Emerging hair fibers were surrounded by a thick, compact sheath of cornified cells. Mutant skin contained large mitochondria with lamellar-shaped, electron-dense structures at the ultrastructural level. Keratohyalin granules were smaller and less pleomorphic than those in control mice. Lamellar bodies were not evident in either mutant or littermate control mice. Using a panel of antibodies to evaluate changes in keratinocyte differentiation, mouse-specific keratin 6 was overexpressed in the suprabasilar, hyperplastic epidermis. Loricrin expression, within the cytoplasm of cells in the stratum granulosum, decreased rapidly postmortem, unlike that in normal mice where it was stable for over 24 hours postmortem. Filaggrin expression, within granules of cells in the stratum granulosum, was prominent, corresponding to hypergranulosis evident by light microscopy in mutant mouse skin. Skin grafts from harlequin ichthyosis mice grafted onto immunodeficient nude mice maintained the phenotype for the 10-week observation period. The mutant gene locus mapped to the proximal end of mouse chromosome 19 and is inherited as a fully penetrant autosomal recessive gene. The harlequin ichthyosis mouse mutation is very similar to human type 2 harlequin ichthyosis for which it may be a good model.

Abstract
An autosomal recessive genetic disease with clinical and histopathological skin features resembling human psoriasis vulgaris occurs naturally in flaky skin mice (fsn/fsn). Affected mice are normal at birth, except for a hypochromic anemia. Subsequently, they develop hyperkeratotic plaques and acanthosis with elongation of rete ridges. Scanning electron microscopic examination revealed a greatly thickened epidermis, a sparsity of hairs and scale accumulations on the epidermal surface. Hair shafts had conspicuous pits, striations, and exophytic protrusions. Nails were bent at a 90 degrees angle with surface irregularities and accumulations of scale at the nail base. Transmission electron microscopic examination showed increased epidermal thickness, mitochondrial aberrations, and intraepidermal invasion by neutrophils. Keratohyalin abnormalities were detected using immunocytochemical staining for profilaggrin. At the dermal-epidermal junction, numerous macrophages and mast cells were seen in close proximity to focal dissolutions of the basement membrane. A high density of collagen fibers and cellular infiltrates were evident in the papillary dermis. This constellation of ultrastructural aberrations is typically found in psoriasis vulgaris and supports the theory that the flaky skin mouse mutation is a naturally occurring analog to one variety of human psoriasis vulgaris.

Abstract
C57BL/Ka mice with chronic proliferative dermatitis (cpdm/cpdm) develop chronic persistent skin lesions characterized by epidermal hyperplasia, infiltration by granulocytes and macrophages, and vascular dilatation. Similar lesions are present in other orthokeratotic epithelia in affected mice, in particular the esophagus and forestomach. Here, we report on further characterization of epidermal hyperplasia and the granulocytes. Keratinocytes of lesional skin, but not of normal skin, show round and electron-dense mitochondrial inclusions that are present in all layers of the epidermis. Similar inclusions are also present in the esophagus and forestomach of affected mice. There appears to be a direct relation between the presence of intramitochondrial inclusions and epidermal hyperplasia in the mouse. Furthermore, the presence of keratinocyte-derived apoptotic bodies in the epidermis, esophagus, and forestomach was frequently observed in the lesions, which is consistent with previous light microscopic observations of single cell death of keratinocytes. The granulocytes present in the skin, esophagus, and forestomach were mainly eosinophils. There were widespread gaps observed in the lamina densa in the epidermis that were mostly directly associated with dermal or epidermal eosinophils. This type of gap is also observed in psoriasiform diseases in humans. This electron microscopic study demonstrated that this mouse model should be useful to screen potential therapeutic strategies for psoriasiform and other inflammatory skin disorders.

Abstract
The ultrastructure of hairless mouse skin exposed to UVB radiation and followed by retinoic acid treatment was studied to identify alterations induced in both epidermis and dermis. Female mice were irradiated 3 times weekly for 5-6 months; a group of these mice was then treated topically 3 times weekly for 10 weeks with either 25 micrograms all-trans-retinoic acid dissolved in acetone or with acetone alone. Age-matched, unexposed, untreated mice served as controls. Cutaneous changes induced by UVB radiation included keratinocyte mitochondrial inclusions often accompanied by damaged cristae, duplication of basement membrane, increased number of dermal fibroblasts, inflammatory cells and elastic fibers, and abnormal elastic fibers. Subsequent retinoic acid treatment resulted in more prominent mitochondrial inclusions which sometimes coalesced to form irregular contoured bodies. Also observed were lipid droplets in the stratum corneum, glycogen deposits in keratinocytes and granular material in dilated keratinocyte endoplasmic reticulum. Poorly differentiated epidermis with necrotic or apoptotic cells was present in some specimens. Elastic fibers were fewer and usually morphologically normal. Skin exposed to UVB and treated with vehicle appeared similar to control except for the presence of excess basement membrane and occasional small mitochondrial inclusions. Because of the heightened concern regarding UV radiation-induced damage to the human skin and the current topical use of retinoids, the cutaneous changes described are considered worthy of attention.

Abstract
Mitochondrial inclusions were observed in keratinocytes during an ultrastructural investigation of the skin of hairless mice exposed to UVB radiation. Mice were irradiated 3 times a week for 5-6 months with sunlamps at individual doses seldom exceeding 0.06 J/cm2. Strips of dorsal skin were processed for electron microscopic examination; blocks were sectioned to include both epidermis and dermis. Mitochondrial inclusions were observed in keratinocytes of the basal, spinous and granular layers. They were spherical in shape and of moderate and homogeneous electron density. Mitochondria toward the upper regions of the epidermis were swollen and had fragmented cristae; mitochondria in the lower areas of the epidermis usually contained smaller and less dense inclusions and intact or partially disrupted cristae. Because mitochondria are essential in providing the energy for cellular function, keratinocyte mitochondrial damage induced by UVB radiation may have serious pathological consequences. Possible mechanisms involved in mitochondrial inclusion formation are suggested.

Abstract
Repeated epilation (Er) is a radiation-induced, autosomal, incomplete dominant mutation in mice which is expressed in heterozygotes but is lethal in the homozygous condition. Many effects of the mutation occur in skin: the epidermis in Er/Er mice is adhesive (oral and nasal orifices fuse, limbs adhere to the body wall), hyperplastic, and fails to undergo terminal differentiation. Skin from fetal +/+, Er/+ and Er/Er mice at ages pre- and postkeratinization examined by light, scanning, and transmission electron microscopy showed marked abnormalities in tissue architecture, differentiation, and cell structure; light and dark basal epidermal cells were separated by wide intercellular spaces, joined by few desmosomes, and contained phagolysomes. The numbers of spinous, granular, and superficial layers were highly variable within any given region and among various regions of the body. In some areas, 2-8 layers of granular cells, containing large or diminutive keratohyalin granules, extended to the epidermal surface; in others, the granular layers were covered by several layers of partially keratinized or nonkeratinized cells. In rare instances, a single or small group of cornified cells was present among the granular layers but was not associated with the epidermal surface. Both the granular and nonkeratinized/partially keratinized upper epidermal layers Er/Er skin gave positive immunofluorescence with antiserum to the histidine-rich, basic protein, filaggrin. Proteins in epidermal extracts from +/+, Er/+ and Er/Er mice were separated and identified by radio- and immunolabeling techniques. The Er/Er extract was missing a 26.5- kdalton protein and had an altered ratio of bands in the keratin region. The 26.5-kdalton band was histidine-rich and cross-reacted with the antiserum to rat filaggrin. Several high molecular weight bands present in both Er/Er and +/+ extracts also reacted with the antiserum. These are presumed to be the precursors of filaggrin and to account for the immunofluorescence om Er/Er epidermis even though the product protein is absent. The morphologic and biochemical data indicated that the genetic defect has a general and profound influence on epidermal differentiation, including alteration of two proteins (filaggrin and keratin) important in normal terminal differentiation, tissue architecture, and cytology. Identification of epidermal abnormalities at early stages of development (prekeratinization) and defective structure of other tissues and gross anatomy suggest that the mutation is responsible for a defect in same regulatory step important in many processes of differentiation and development.

Abstract
The responses of hairless mouse epidermis to tape stripping, ethanol and vitamin A acid were compared using electron microscopy and cytochemistry. Stripping the skin 4 times with cellophane tape removed most of the stratum corneum and caused the development of enlarged intercellular spaces and dense intramitochondrial inclusions. These changes began within an hour, reached a maximum by 24 hr, and subsided by about 4 days. There was also some accumulation of glycogen and the development of occasional basal lamina breaks and a few intracellular lipid droplets by 24 hr. Topically applied ethanol (95%) produced a similar response, though less damaging. In addition, ethanol induced the formation of numerous lipid droplets in the cytoplasm of keratinocytes by 24 hr and often caused sloughing of the stratum corneum. Vitamin A acid (3%) was dissolved in propylene glycol for application to the skin. We found the application of propylene glycol alone to produce no epidermal changes. Vitamin A acid produced mild damaging effects with small intercellular spaces and intramitochondrial inclusions, but no lipid droplets or glycogen were detected. Vitamin A acid also caused dramatic inhibition of keratinization by 24 hr. Intramitochondrial inclusions were digested by protease, indicating a protein component and they also stained with silver methenamine, indicating the presence of glycogen or glycoprotein.

Abstract
"Intramitochondrial filamentous bodies" (IMFB) were occasionally found within the matrix of some mitochondria of the thick limb of Henle of the rat kidney, but not elsewhere in the tubular system. Three types were recognized: type I, an accumulation of filaments 55 A thick; type II, a bundle of parallel filaments having the same thickness as those of type I and regular spacing, 87 A apart, from center to center; and type III, consisting of type II with regular light bands of 280 A periodicity and a helical border of prismatic tubular cristae. In addition to these, electron-opaque masses showing variable and faint substructures were found in the matrix of mitochondria. It is suggested that all these IMFB may originate from mitochondrial cristae and that type II IMFB may be an intermediate developmental form between type I and type III. After uranyl acetate staining, IMFB and the membranes of prismatic tubular cristae showed highly increased electron opacity. The literature has been reviewed for reports of intramitochondrial filamentous inclusions in various types of cells. These inclusions have been classified according to their structural characteristics and the localization in the mitochondria and compared with IMFB reported herein.

Abstract
A minute cylindrical structure with a dense core, designated as "microcylinder," has been observed within enlarged spaces of mitochondrial cristae in pinealocytes of some adult rats (osmium tetroxide fixed, methacrylate embedded). The microcylinders are 270 to 330 A in diameter and of indeterminate length. Their wall is found to be made up of slender filamentous subunits, probably 6 in number, and surrounds a central filament. The microcylinders are arranged parallel to one another, forming monolayered or, more frequently, multilayered aggregates. Their number within a crista varies considerably. Packets of microcylinders may be seen located in the outer mitochondrial chamber, but are never found in the mitochondrial matrix. They have been observed neither in other cell types of the pineal gland nor in neurons, ependymal, and glial cells of the nearby epithalamic tissue. The origin and nature of the microcylinders are unknown. Glycogen-like particles have been encountered, though very infrequently, accompanying bundles of microcylinders within mitochondrial cristae.
