INTEGUMENTARY SYSTEM - Illnesses and disorders... Unlike some other body systems, the integumentary system quickly shows when it is struck by an injury or disorder. Over one thousand different disorders can affect the skin. The most common skin disorders are those caused by allergies or bacterial or fungal infections. Burns and skin cancers, although less common, are more dangerous. In some cases, they can be lethal. The following are just a few of the many disorders that can target the integumentary system. Acne Acne is a skin disease marked by pimples on the face, chest, and back. The most common skin disease, acne, affects an estimated 17 to 28 million people in the United States. Although it can strike people at any age, acne usually begins at puberty and worsens during adolescence. At puberty, increased levels of androgens (male hormones) cause the sebaceous glands to secrete an excessive amount of sebum into hair follicles. The excess sebum combines with dead, ...

Paleontologia Geral 2016Alternatively, if scales were indeed the dominant integumentary structures in most Late Cretaceous tyrannosauroids, the presence of long feathers in the gigantic Y. huali could represent an adaptation to an unusually cold environment. Y. huali lived during a period (the Barremian-early Albian) that has been interpreted as considerably colder than the rest of the Cretaceous (a mean annual air temperature of about 10 °C in western Liaoning, in contrast with about 18 °C at a similar latitude in the Late Cretaceous)27. Most gigantic Late Cretaceous tyrannosauroids, by contrast, lived in a warm climate that was conducive to the loss of an extensive insulative feathery covering, although populations inhabiting cold environments such as the land that is now Alaska would have been a notable exception28, 29. It is possible that the extent and nature of the integumentary covering changed over time in response to shifts in body size and the temperature of the environment throughout ...

(1/75) Covering the limb--formation of the integument.
An organism's outermost covering, the integument, has evolved to fulfil a diverse range of functions. Skin provides a physical barrier, an environment for immunological surveillance, and also performs a range of sensory, thermoregulatory and biosynthetic functions. Examination of the skin of limb digits reveals a range of skin types including the thickened hairless epidermis of the toe pads (palmar or plantar epidermis) and thinner epidermis between the hair follicles (interfollicular epidermis) of hairy skin. An important developmental function of skin is to give rise to a diverse group of appendages including hair follicles, with associated sebaceous glands (or feathers and scales in chick), eccrine sweat glands and the nail. A key question is how does this morphological variety arise from the single-layered epithelium covering embryonic limb buds? This review will attempt to address this question by linking the extensive morphological/anatomical data on maturation of epidermis and its appendages with (1) current research into the range, plasticity and location of the putative epidermal stems cells; (2) molecular/microenvironmental regulation of epidermal stem cell lineages and lineage choice; and (3) regulation of the differentiation pathways, focusing on differentiation of the interfollicular epidermis.

(2/75) Tegumental ultrastructure of the juvenile and adult Himasthla alincia (Digenea: Echinostomatidae).
The tegumental ultrastructure of juvenile and adult Himasthla alincia (Digenea: Echinostomatidae) was observed by scanning electron microscopy. One-, 5- (juveniles) and 20-day-old worms (adults) were harvested from chicks experimentally fed metacercariae from a bivalve, Mactra veneriformis. The juvenile worms were elongated and curved ventrally. The head crown bore 31 collar spines, arranged in a single row. The lip of the oral sucker had 12 paired, and 3 single type I sensory papillae, and the ventral sucker had about 25 type II sensory papillae. The anterolateral surface between the two suckers was densely packed with tegumental spines with 4-7 pointed tips. The adult worms were more elongated and filamentous, and had severe transverse folds over the whole body surface. On the head crown and two suckers, type I and II sensory papillae were more densely distributed than in the juvenile worms. Retractile brush-like spines, with 8-10 digits, were seen on the anterolateral surface, whereas claw-shaped spines, with 2-5 digits, were sparsely distributed posteriorly to the ventral sucker. The cirrus characteristically protruded out, and was armed with small spines distally. The surface ultrastructure of H. alincia was shown to be unique among echinostomes, especially in the digitation of its tegumental spines, the distribution of sensory papillae and by severe folds of the tegument.

(3/75) Chemical defence in a sawfly: genetic components of variation in relevant life-history traits.
Larvae of several tenthredinid sawfly species readily release droplets of haemolymph through their integument when attacked by predators. This defence mechanism via 'bleeding' is characterised by a low integument resistance and a high haemolymph deterrence. Both traits are variable, and negatively correlated among species. We sought to determine if such differences in the propensity to bleed also occur intraspecifically by studying the heritability of traits potentially associated with the bleeding phenomenon in the turnip sawfly Athalia rosae ruficornis Jakovlev (Hymenoptera: Tenthredinidae, Allantinae). For three European populations, heritabilities were estimated in the laboratory in a parent-offspring and a full-sib design for haemolymph deterrence (measured as concentration of sequestered glucosinolate), integument resistance, body mass of eonymph and adult, and developmental time. Within A. rosae, no significant negative phenotypic correlation was found between the two traits directly related to the defence mechanism: integument resistance and haemolymph deterrence. However, the significant heritabilities found for these traits in the full-sib analysis (0.39 and 0.35, respectively, for males in the Swiss population) show that the variation has a genetic component. While full-sib analysis revealed highly significant heritabilities for most traits in all the three populations, parent-offspring regression revealed little or no evidence of heritable variation. Effects of common environment for siblings and variation in the host-plant quality between insect generations are likely to be the main factors explaining these differences. A consequence of such host-plant variation in the wild might be that genetic variation of such chemical defensive traits is largely invisible to natural selection. (+info)
(4/75) Morpho-regulation of ectodermal organs: integument pathology and phenotypic variations in K14-Noggin engineered mice through modulation of bone morphogenic protein pathway.
Ectodermal organs are composed of keratinocytes organized in different ways during induction, morphogenesis, differentiation, and regenerative stages. We hypothesize that an imbalance of fundamental signaling pathways should affect multiple ectodermal organs in a spatio-temporal-dependent manner. We produced a K14-Noggin transgenic mouse to modulate bone morphogenic protein (BMP) activity and test the extent of this hypothesis. We observed thickened skin epidermis, increased hair density, altered hair types, faster anagen re-entry, and formation of compound vibrissa follicles. The eyelid opening was smaller and ectopic cilia formed at the expense of Meibomian glands. In the distal limb, there were agenesis and hyperpigmentation of claws, interdigital webbing, reduced footpads, and trans-differentiation of sweat glands into hairs. The size of external genitalia increased in both sexes, but they remained fertile. We conclude that modulation of BMP activity can affect the number of ectodermal organs by acting during induction stages, influence the size and shape by acting during morphogenesis stages, change phenotypes by acting during differentiation stages, and facilitate new growth by acting during regeneration stages. Therefore during organogenesis, BMP antagonists can produce a spectrum of phenotypes in a stage-dependent manner by adjusting the level of BMP activity. The distinction between phenotypic variations and pathological changes is discussed. (+info)
(5/75) A novel mouse type I intermediate filament gene, keratin 17n (K17n), exhibits preferred expression in nail tissue.
Inactivating the type I keratin 17 gene (mK17) causes severe but reversible hair loss in a strain-dependent fashion in mouse (McGowan et al, Genes Dev. 16:1412, 2002). Missense mutations in human K17 give rise to two dominantly inherited disorders apparented to ectodermal dysplasias, pachyonychia congenita (PC), and steatocystoma multiplex (SM). In contrast to the null phenotype in mouse, marked lesions are seen in the nail and nail bed and sebaceous glands of PC and SM patients, respectively. In an effort to understand the lack of nail involvement in mK17 null mice, we discovered that the gene located immediately 5' upstream from mK17 is functional and encodes a type I keratin protein highly analogous to mK17. mRNA and protein localization studies show that the expression of this novel gene is highly restricted and most prevalent in the nail bed and matrix, leading to its designation as mK17n (n stands for nail). Weak expression of mK17n also occurs in vibrissae follicles, in filiform and fungiform papillae of oral mucosa. These findings have direct implications for the mK17 null phenotype. Depending on the existence of a human ortholog or a functional equivalent, our findings may also provide a molecular explanation for several unusual aspects of hK17-based diseases. (+info)
(6/75) Ultrastructure of the tegument of Metamicrocotyla macracantha (Alexander, 1954) Koratha, 1955 (Monogenea, Microcotylidae).
The ultrastructure of the body tegument of Metamicrocotyla macracantha (Alexander, 1954) Koratha, 1955, parasite of Mugil liza from Brazil, was studied by transmission electron microscopy. The body tegument is composed of an external syncytial layer, musculature, and an inner layer containing tegumental cells. The syncytium consists of a matrix containing three types of body inclusions and mitochondria. The musculature is constituted of several layers of longitudinal and circular muscle fibers. The tegumental cells present a well-developed nucleus, cytoplasm filled with ribosomes, rough endoplasmatic reticulum and mitochondria, and characteristic organelles of tegumental cells. (+info)
(7/75) Integument pattern formation involves genetic and epigenetic controls: feather arrays simulated by digital hormone models.
Pattern formation is a fundamental morphogenetic process. Models based on genetic and epigenetic control have been proposed but remain controversial. Here we use feather morphogenesis for further evaluation. Adhesion molecules and/or signaling molecules were first expressed homogenously in feather tracts (restrictive mode, appear earlier) or directly in bud or inter-bud regions ( de novo mode, appear later). They either activate or inhibit bud formation, but paradoxically colocalize in the bud. Using feather bud reconstitution, we showed that completely dissociated cells can reform periodic patterns without reference to previous positional codes. The patterning process has the characteristics of being self-organizing, dynamic and plastic. The final pattern is an equilibrium state reached by competition, and the number and size of buds can be altered based on cell number and activator/inhibitor ratio, respectively. We developed a Digital Hormone Model which consists of (1) competent cells without identity that move randomly in a space, (2) extracellular signaling hormones which diffuse by a reaction-diffusion mechanism and activate or inhibit cell adhesion, and (3) cells which respond with topological stochastic actions manifested as changes in cell adhesion. Based on probability, the results are cell clusters arranged in dots or stripes. Thus genetic control provides combinational molecular information which defines the properties of the cells but not the final pattern. Epigenetic control governs interactions among cells and their environment based on physical-chemical rules (such as those described in the Digital Hormone Model). Complex integument patterning is the sum of these two components of control and that is why integument patterns are usually similar but non-identical. These principles may be shared by other pattern formation processes such as barb ridge formation, fingerprints, pigmentation patterning, etc. The Digital Hormone Model can also be applied to swarming robot navigation, reaching intelligent automata and representing a self-re-configurable type of control rather than a follow-the-instruction type of control.

(8/75) Evo-Devo of amniote integuments and appendages.
Integuments form the boundary between an organism and the environment. The evolution of novel developmental mechanisms in integuments and appendages allows animals to live in diverse ecological environments. Here we focus on amniotes. The major achievement for reptile skin is an adaptation to the land with the formation of a successful barrier. The stratum corneum enables this barrier to prevent water loss from the skin and allowed amphibian / reptile ancestors to go onto the land. Overlapping scales and production of beta-keratins provide strong protection. Epidermal invagination led to the formation of avian feather and mammalian hair follicles in the dermis. Both adopted a proximal - distal growth mode which maintains endothermy. Feathers form hierarchical branches which produce the vane that makes flight possible. Recent discoveries of feathered dinosaurs in China inspire new thinking on the origin of feathers. In the laboratory, epithelial - mesenchymal recombinations and molecular mis-expressions were carried out to test the plasticity of epithelial organ formation. We review the work on the transformation of scales into feathers, conversion between barbs and rachis and the production of "chicken teeth". In mammals, tilting the balance of the BMP pathway in K14 noggin transgenic mice alters the number, size and phenotypes of different ectodermal organs, making investigators rethink the distinction between morpho-regulation and pathological changes. Models on the evolution of feathers and hairs from reptile integuments are discussed. A hypothetical Evo-Devo space where diverse integument appendages can be placed according to complex phenotypes and novel developmental mechanisms is presented. (+info)
