Sebum
Sebaceous Glands
Small, sacculated organs found within the DERMIS. Each gland has a single duct that emerges from a cluster of oval alveoli. Each alveolus consists of a transparent BASEMENT MEMBRANE enclosing epithelial cells. The ducts from most sebaceous glands open into a HAIR FOLLICLE, but some open on the general surface of the SKIN. Sebaceous glands secrete SEBUM.
Acne Vulgaris
Dermatitis, Seborrheic
A chronic inflammatory disease of the skin with unknown etiology. It is characterized by moderate ERYTHEMA, dry, moist, or greasy (SEBACEOUS GLAND) scaling and yellow crusted patches on various areas, especially the scalp, that exfoliate as dandruff. Seborrheic dermatitis is common in children and adolescents with HIV INFECTIONS.

The role of specific retinoid receptors in sebocyte growth and differentiation in culture. (1/82)
Retinoic acid derivatives (retinoids) exert their pleiotropic effects on cell development through specific nuclear receptors, the retinoic acid receptors and retinoid X receptors. Despite recent progress in understanding the cellular and molecular mechanisms of retinoid activity, it is unknown which of the retinoid receptor pathways are involved in the specific processes of sebocyte growth and development. In this study, we investigated the roles of specific retinoid receptors in sebocyte growth and differentiation, by testing the effects of selective retinoic acid receptor and retinoid X receptor ligands at concentrations between 10-10 M and 10-6 M in a primary rat preputial cell monolayer culture system. Cell growth was determined by number of cells and colonies, and cell differentiation by analysis of lipid-forming colonies. All-trans retinoic acid and selective retinoic acid receptor agonists (CD271 = adapalene, an RAR-beta,gamma agonist; CD2043 = retinoic acid receptor pan-agonist; and CD336 = Am580, an RAR-alpha agonist) caused significant decreases in numbers of cells, colonies, and lipid-forming colonies, but with an exception at high doses of all-trans retinoic acid (10-6 M), with which only a small number of colonies grew but they became twice as differentiated as controls (42.2 +/- 4.0% vs 22.6 +/- 2.7%, mean +/- SEM, lipid-forming colonies, p < 0.01). Furthermore, the RAR-beta,gamma antagonist CD2665 antagonized the suppressive effects of all-trans retinoic acid, adapalene, and CD2043 on both cell growth and differentiation. In contrast, the retinoid X receptor agonist CD2809 increased cell growth slightly and lipid-forming colonies dramatically in a clear dose-related manner to a maximum of 73.7% +/- 6.7% at 10-6 M (p < 0. 001). Our data suggest that retinoic acid receptors and retinoid X receptors differ in their roles in sebocyte growth and differentiation: (i) retinoic acid receptors, especially the beta and/or gamma subtypes, mediate both the antiproliferative and antidifferentiative effects of retinoids; (ii) retinoid X receptors mediate prominent differentiative and weak proliferative effects; (iii) the antiproliferative and antidifferentiative effects of all-trans retinoic acid are probably mediated by retinoic acid receptors, whereas its differentiative effect at high dose may be mediated by retinoid X receptors via all-trans retinoic acid metabolism to 9-cis retinoic acid, the natural ligand of retinoid X receptors. (+info)Dehydroepiandrosterone (DHEA), DHEA sulfate, and aging: contribution of the DHEAge Study to a sociobiomedical issue. (2/82)
The secretion and the blood levels of the adrenal steroid dehydroepiandrosterone (DHEA) and its sulfate ester (DHEAS) decrease profoundly with age, and the question is posed whether administration of the steroid to compensate for the decline counteracts defects associated with aging. The commercial availability of DHEA outside the regular pharmaceutical-medical network in the United States creates a real public health problem that may be resolved only by appropriate long-term clinical trials in elderly men and women. Two hundred and eighty healthy individuals (women and men 60-79 years old) were given DHEA, 50 mg, or placebo, orally, daily for a year in a double-blind, placebo-controlled study. No potentially harmful accumulation of DHEAS and active steroids was recorded. Besides the reestablishment of a "young" concentration of DHEAS, a small increase of testosterone and estradiol was noted, particularly in women, and may be involved in the significantly demonstrated physiological-clinical manifestations here reported. Bone turnover improved selectively in women >70 years old, as assessed by the dual-energy x-ray absorptiometry (DEXA) technique and the decrease of osteoclastic activity. A significant increase in most libido parameters was also found in these older women. Improvement of the skin status was observed, particularly in women, in terms of hydration, epidermal thickness, sebum production, and pigmentation. A number of biological indices confirmed the lack of harmful consequences of this 50 mg/day DHEA administration over one year, also indicating that this kind of replacement therapy normalized some effects of aging, but does not create "supermen/women" (doping). (+info)13-cis retinoic acid exerts its specific activity on human sebocytes through selective intracellular isomerization to all-trans retinoic acid and binding to retinoid acid receptors. (3/82)
Despite its potent biologic effect on human sebocytes, 13-cis retinoic acid exhibits low binding affinity for cellular retinoic acid binding proteins and nuclear retinoid receptors. Hence, 13-cis retinoic acid may represent a pro-drug possibly acting through all-trans isomerization. In this study, marked isomerization of 13-cis retinoic acid has been confirmed in cultured SZ95 sebocytes showing 2- to 15-fold higher levels of all-trans retinoic acid at 12-72 h, as measured by high performance liquid chromatography. In contrast, only low amounts of all-trans retinoic acid were converted intracellularly to its 13-cis isoform. 9-cis retinoic acid was not detected after either 13-cis retinoic acid or all-trans retinoic acid treatment. The rapid isomerization of 13-cis retinoic acid to high levels of all-trans retinoic acid was a sebocyte-specific event, as no significant isomerization of 13-cis retinoic acid to all-trans retinoic acid occurred in HaCaT keratinocytes. De novo mRNA expression of cytochrome P450 1A1, a major xenobiotic metabolizing enzyme, in SZ95 sebocytes was induced by all-trans retinoic acid, but not by 13-cis retinoic acid. In addition, mRNA levels of cellular retinoic acid-binding protein II, which is supposed to regulate the concentration of intracellular all-trans retinoic acid, rapidly increased under all-trans retinoic acid treatment (30 min-6 h), whereas the 13-cis retinoic acid effect was markedly weaker and delayed. Both 13-cis retinoic acid and all-trans retinoic acid suppressed mRNA expression of cytochrome P450 1A2. In parallel experiments, 13-cis retinoic acid significantly reduced SZ95 sebocyte proliferation at 10-7 M, show- ing 30-40% inhibition after 9 d. All-trans retinoic acid and 9-cis retinoic acid exhibited similar anti-proliferative effects. AGN 193109, a pan-antagonist of the retinoic acid receptors, antagonized the anti-proliferative activity of all retinoic acid isomers tested in a concentration-dependent manner with complete abolishment at ratios of 1:10 13-cis retinoic acid and 1:1 all-trans retinoic acid. Coincubation of SZ95 sebocytes with 13-cis retinoic acid and AGN 193109 did not alter the intracellular concentration of 13-cis retinoic acid and its isomerization profile. In contrast, the retinoid X receptor antagonist CD 3507 did not affect the inhibition of SZ95 sebocyte proliferation induced by retinoic acids. Our findings indicate: (i) a selective 13-cis retinoic acid isomerization to all-trans retinoic acid in the intracellular compartment of SZ95 sebocytes; (ii) a reduced all-trans retinoic acid inactivation process after 13-cis retinoic acid treatment as compared with treatment with all-trans retinoic acid; and (iii) a retinoic acid receptor-mediated inhibition of SZ95 sebocyte proliferation. These data explain the sebocyte-specific activity of 13-cis retinoic acid and support a pro-drug/drug relation between 13-cis retinoic acid and all-trans retinoic acid. (+info)The melanocortin 5 receptor is expressed in human sebaceous glands and rat preputial cells. (4/82)
Melanocortins regulate pigmentation, adrenal hormone secretion, immune functions, lipid metabolism, and feeding behaviors in rodents. These peptides include adrenocorticotrophic hormone, melanocyte stimulating hormone, beta-lipotrophin, and the endorphins. Lipid metabolism in sebaceous glands and preputial glands of rodents is regulated by alpha-melanocyte stimulating hormone, the major agonist for melanocortin receptors. Five melanocortin receptor subtypes have been identified that differ in their tissue localization and affinities for melanocortin ligands. Targeted disruption of the melanocortin 5 receptor in transgenic mice results in widespread dysfunction of exocrine glands, including a marked decrease in sebum production. A role for melanocortins in the modulation of human sebum production has not been established. The goal of this study is to determine which melanocortin receptors are expressed in human sebaceous glands. Messenger RNA was isolated from human sebaceous glands and the reverse transcriptase polymerase chain reaction was performed using primers specific for each of the melanocortin receptor subtypes. Transcripts were detected for the melanocortin 5 receptor. A polyclonal chicken antihuman antibody to the melanocortin 5 receptor localized to sebaceous glands, eccrine glands, hair follicles, and epidermis in human skin, rat skin, cultured human sebocytes, and rat preputial cells. Presence of the melanocortin 5 receptor protein in human sebaceous glands and rat preputial glands was further verified by Western blotting. These data support further investigation of the role of melanocortins in the regulation of human sebum production and support the use of the rat preputial system as an experimental model in sebaceous gland physiology. (+info)Attenuated total reflection-Fourier transform infrared spectroscopy as a possible method to investigate biophysical parameters of stratum corneum in vivo. (5/82)
We investigated the use of attenuated total reflection-Fourier transform infrared spectroscopy as a method to study differences in the molecular components of human stratum corneum in vivo. These variations as a function of the anatomic site and of the depth into its layered structure are important to understand the biology and physiology of the tissue. In this preliminary study we have investigated spectroscopic changes in 18 healthy individuals. Total reflection-Fourier transform infrared spectroscopy represents a potentially powerful tool to study biophysical properties of surfaces. We observed that, in vivo, biophysical parameters of the stratum corneum (such as hydration, lipid composition, and conformation of the aliphatic chains) are indeed dependent on the anatomic site. As in total reflection-Fourier transform infrared spectroscopy experiments the penetration depth of the evanescent field into the stratum corneum is comparable with the thickness of a layer of corneocytes, this technique can be used to follow the distribution of lipids, water, and proteins as a function of depth into the tissue. We found that, in vivo, these molecular components are non-uniformly distributed, in agreement with the presence of water and lipid reservoirs as observed with ex vivo ultrastructural investigations. Composition and conformational order of lipids are also a function of depth into the stratum corneum. Finally we compared the in vivo superficial hydration measured using the infrared absorption of the OH stretch of water, with the hydration measured using the Skicon hygrometer. Our results indicate that total reflection-Fourier transform infrared spectroscopy might be useful to measure important chemical and biophysical parameters of stratum corneum in vivo. (+info)The influence of two azones and sebaceous lipids on the lateral organization of lipids isolated from human stratum corneum. (6/82)
The main problem with topical application of compounds to administer drugs to and regulate drug levels in a human body, is the barrier formed by the intercellular lipid matrix of the stratum corneum (SC). In a search for possibilities to overcome this barrier function, a good understanding of the organization and phase behavior of these lipids is required. SC lipid model studies especially provide a wealth of information with respect to the lipid organization and the importance of certain subclasses of lipids for the structure. Previously, we have shown that electron diffraction (ED) provides detailed information on the lateral lipid packing in both intact SC (G.S.K. Pilgram et al., J. Invest. Dermatol. 113 (1999) 403) and SC lipid models (G.S.K. Pilgram et al., J. Lipid Res. 39 (1998) 1669). In the present study, we used ED to examine the influence of two azones and sebaceous lipids on the lateral phase behavior of lipids isolated from human SC. We established that human SC lipids are arranged in an orthorhombic packing pattern. Upon mixing with the two enhancers the orthorhombic packing pattern was still observed; however, an additional fluid phase became more apparent. In mixtures with sebaceous lipids, the presence of the hexagonal lattice increased. These findings provide a basis for the mechanism by which these enhancers and sebaceous lipids interact with human SC lipids. (+info)Sebocytes are the key regulators of androgen homeostasis in human skin. (7/82)
The mRNA expression patterns of the androgen receptor and the androgen metabolizing enzymes 3beta-hydroxysteroid dehydrogenase/Delta(5-4)-isomerase, 17beta-hydroxysteroid dehydrogenase, 5alpha-reductase, and 3alpha-hydroxysteroid dehydrogenase were investigated in three different cell populations originating from human skin, SZ95 sebocytes, HaCaT keratinocytes, and MeWo melanoma cells, by means of reverse transcription polymerase chain reaction. Restriction analysis of cDNA fragments was performed to identify isozymes of 3beta-hydroxysteroid dehydrogenase/Delta(5-4)-isomerase and 3alpha-hydroxysteroid dehydrogenase. In addition, 3H-dihydroepiandrosterone and 3H-testosterone were used as substrates to determine the metabolic activity of these enzymes in SZ95 sebocytes, primary sebocyte cultures, and HaCaT keratinocytes. Furthermore, the effects of the selective 5alpha-reductase type 1 and 2 inhibitors, 4,7beta-dimethyl-4-aza-5alpha-cholestan-3-one and dihydrofinasteride, respectively, and of the 3beta-hydroxysteroid dehydrogenase/Delta(5-4)-isomerase inhibitor cyproterone acetate on androgen metabolism were investigated. Androgen receptor mRNA was detected in SZ95 sebocytes and HaCaT keratinocytes but not in MeWo melanoma cells, whereas 3beta-hydroxysteroid dehydrogenase/Delta(5-4)-isomerase isotype 1 mRNA and metabolic activity were only found in SZ95 sebocytes. The enzyme activity could be inhibited by cyproterone acetate. Type 2 17beta-hydroxysteroid dehydrogenase, type 1 5alpha-reductase, and 3alpha-hydroxysteroid dehydrogenase mRNA were expressed in all three cell populations tested, whereas type 3 17beta-hydroxysteroid dehydrogenase mRNA could only be detected in SZ95 sebocytes. The major metabolic steps of testosterone in SZ95 sebocytes, primary sebocyte cultures, and HaCaT keratinocytes were its conversion to androstenedione by 17beta-hydroxysteroid dehydrogenase and further to 5alpha-androstanedione by 5alpha-reductase. The type 1 5alpha-reductase selective inhibitor 4,7beta-dimethyl-4-aza-5alpha-cholestan-3-one, but not the type 2 selective inhibitor dihydrofinasteride, inhibited 5alpha-reductase at low concentrations in SZ95 sebocytes and HaCaT keratinocytes. 5alpha-androstanedione was degraded to androsterone by 3alpha-hydroxysteroid dehydrogenase, which exhibited a stronger activity in HaCaT keratinocytes than in SZ95 sebocytes and in primary sebocyte cultures. Lower levels of 5alpha-dihydrotestosterone and 5alpha-androstanediol were also detected in all cells tested. Our investigations show that specific enzyme expression and activity in cultured sebocytes and keratinocytes seem to allocate different duties to these cells in vitro. Sebocytes are able to synthesize testosterone from adrenal precursors and to inactivate it in order to maintain androgen homeostasis, whereas keratinocytes are responsible for androgen degradation. (+info)Why do we have apocrine and sebaceous glands? (8/82)
The secretions of sebaceous and apocrine glands fulfil an important thermoregulatory role in cold-stressed and heat-stressed hunter-gatherers. In hot conditions the secretions emulsify eccrine sweat and thus encourage the formation of a sweat sheet and discourage the formation and loss of sweat drops from the skin. In colder conditions sebum changes its nature and repels rain from skin and hair. (+info)"Sebum is a natural oily substance produced by the sebaceous glands in the skin, consisting primarily of lipids, that plays a crucial role in maintaining the skin's barrier function and hair lubrication."
Sebum is an oily, waxy substance that is produced by the sebaceous glands in the skin of mammals. It is composed mainly of triglycerides, wax esters, squalene, and free fatty acids, as well as smaller amounts of metabolites and other substances. Sebum plays an important role in the maintenance of the skin's barrier function and in the regulation of its moisture levels. It also has antimicrobial properties that help to protect the skin from infection. Excessive sebum production can contribute to the development of acne and other skin conditions.
Sebaceous glands are microscopic, exocrine organs in the skin that produce and release sebum, an oily substance, to lubricate and waterproof hair and skin, typically associated with the pilosebaceous unit.
Sebaceous glands are microscopic, exocrine glands that are found in the dermis of mammalian skin. They are attached to hair follicles and produce an oily substance called sebum, which is composed of triglycerides, wax esters, squalene, and metabolites of fat-producing cells (fatty acids, cholesterol). Sebum is released through a duct onto the surface of the skin, where it forms a protective barrier that helps to prevent water loss, keeps the skin and hair moisturized, and has antibacterial properties.
Sebaceous glands are distributed throughout the body, but they are most numerous on the face, scalp, and upper trunk. They can also be found in other areas of the body such as the eyelids (where they are known as meibomian glands), the external ear canal, and the genital area.
Abnormalities in sebaceous gland function can lead to various skin conditions, including acne, seborrheic dermatitis, and certain types of skin cancer.
Acne Vulgaris is a common chronic inflammatory skin condition characterized by the formation of comedones, papules, pustules, nodules or cysts, primarily on the face, back and chest, due to obstruction and inflammation of pilosebaceous units.
Acne vulgaris is a common skin condition characterized by the formation of various types of blemishes on the skin, such as blackheads, whiteheads, papules, pustules, and cysts or nodules. These lesions typically appear on areas of the body that have a high concentration of sebaceous glands, including the face, neck, chest, back, and shoulders.
Acne vulgaris occurs when hair follicles become clogged with dead skin cells and excess oil (sebum) produced by the sebaceous glands. This blockage provides an ideal environment for bacteria, particularly Propionibacterium acnes, to multiply, leading to inflammation and infection. The severity of acne vulgaris can range from mild with only a few scattered comedones (blackheads or whiteheads) to severe cystic acne, which can cause significant scarring and emotional distress.
The exact causes of acne vulgaris are not fully understood, but several factors contribute to its development, including:
1. Hormonal changes during puberty, menstruation, pregnancy, or due to conditions like polycystic ovary syndrome (PCOS)
2. Genetic predisposition
3. Use of certain medications, such as corticosteroids and lithium
4. Excessive production of sebum due to overactive sebaceous glands
5. Accumulation of dead skin cells that clog pores
6. Bacterial infection (particularly Propionibacterium acnes)
7. Inflammation caused by the body's immune response to bacterial infection and clogged pores
Treatment for acne vulgaris depends on its severity and can include over-the-counter or prescription topical treatments, oral medications, chemical peels, light therapies, or even hormonal therapies in some cases. It is essential to seek professional medical advice from a dermatologist or healthcare provider to determine the most appropriate treatment plan for individual needs.
Seborrheic dermatitis is a chronic inflammatory skin condition characterized by erythema, scales, and sometimes vesicles or papules, typically occurring in areas with high sebum production such as the scalp, face, and trunk.
Seborrheic dermatitis is a common, inflammatory skin condition that mainly affects the scalp, face, and upper part of the body. It causes skin irritation, flaking, and redness, often in areas where the skin is oily or greasy. The exact cause of seborrheic dermatitis is not fully understood, but it appears to be related to a combination of genetic, environmental, and microbial factors.
The symptoms of seborrheic dermatitis can vary in severity and may include:
* Greasy or flaky scales on the scalp, eyebrows, eyelashes, ears, or beard
* Redness and inflammation of the skin
* Itching, burning, or stinging sensations
* Yellow or white crusty patches on the scalp or other affected areas
* Hair loss (in severe cases)
Seborrheic dermatitis is a chronic condition that tends to flare up and then subside over time. While there is no cure for seborrheic dermatitis, various treatments can help manage the symptoms and prevent complications. These may include medicated shampoos, topical creams or ointments, and lifestyle changes such as stress reduction and avoiding triggers that worsen symptoms.
It is important to note that seborrheic dermatitis should not be confused with other skin conditions, such as psoriasis or eczema, which may have similar symptoms. A healthcare professional can provide a proper diagnosis and recommend appropriate treatment options based on the individual's specific needs.
'Squalene' is a biologically occurring triterpene compound, naturally produced in humans, animals, and plants, that forms an essential part of the lipid-rich membranes in various tissues, including the skin surface and the liver, and has been studied for its potential benefits in skincare, dietary supplements, and vaccine adjuvant systems.
Squalene is a organic compound that is a polyunsaturated triterpene. It is a natural component of human skin surface lipids and sebum, where it plays a role in maintaining the integrity and permeability barrier of the stratum corneum. Squalene is also found in various plant and animal tissues, including olive oil, wheat germ oil, and shark liver oil.
In the body, squalene is an intermediate in the biosynthesis of cholesterol and other sterols. It is produced in the liver and transported to other tissues via low-density lipoproteins (LDLs). Squalene has been studied for its potential health benefits due to its antioxidant properties, as well as its ability to modulate immune function and reduce the risk of certain types of cancer. However, more research is needed to confirm these potential benefits.
The forehead is the anatomical region located on the frontal aspect of the skull, bounded superiorly by the hairline, inferiorly by the eyebrows, and laterally by the temples, consisting primarily of the frontal bone.
A forehead, in medical terms, refers to the portion of the human skull that lies immediately above the eyes and serves as an attachment site for the frontal bone. It is a common area for the examination of various clinical signs, such as assessing the level of consciousness (by checking if the patient's eyebrows or eyelids twitch in response to a light touch) or looking for signs of increased intracranial pressure (such as bulging fontanelles in infants). Additionally, the forehead is often used as a site for non-invasive procedures like Botox injections.
Isotretinoin is a oral retinoid medication, derived from vitamin A, used primarily in the treatment of severe recalcitrant nodular acne and some skin cancers, with teratogenic potential and strict monitoring requirements due to its significant side effects profile.
Isotretinoin is a derivative of vitamin A, used in the treatment of severe recalcitrant nodular acne that has not responded to other therapies. It is a potent inhibitor of sebaceous gland function and keratinization. Isotretinoin is also known to have anti-inflammatory properties. It is taken orally in the form of capsules and its use requires careful monitoring due to potential teratogenic effects and other side effects, such as dryness of the skin and mucous membranes, mood changes, and liver enzyme abnormalities.

In the medical context, lubricants are substances applied to reduce friction between internal body parts or external devices and bodily tissues, primarily used during medical examinations, procedures, or sexual activities to ensure comfort and minimize potential tissue injuries.
Medical definitions of "lubricants" refer to substances that are used to reduce friction between two surfaces in medical procedures or devices. They can be used during various medical examinations, surgeries, or when inserting medical equipment, such as catheters, to make the process smoother and more comfortable for the patient.
Lubricants used in medical settings may include water-based gels, oil-based jellies, or silicone-based lubricants. It's important to choose a lubricant that is safe and suitable for the specific medical procedure or device being used. For example, some lubricants may not be compatible with certain medical materials or may need to be sterile.
It's worth noting that while lubricants are commonly used in medical settings, they should not be used as a substitute for proper medical care or treatment. If you have any concerns about your health or medical condition, it's important to consult with a qualified healthcare professional.

The nose is the externally prominent, upper part of the respiratory system, consisting of paired nasal cavities divided by a midline septum, and functions primarily in the olfaction (smell), filtration, and humidification of atmospheric air for respiration. (AAMC)
A nose, in a medical context, refers to the external part of the human body that is located on the face and serves as the primary organ for the sense of smell. It is composed of bone and cartilage, with a thin layer of skin covering it. The nose also contains nasal passages that are lined with mucous membranes and tiny hairs known as cilia. These structures help to filter, warm, and moisturize the air we breathe in before it reaches our lungs. Additionally, the nose plays an essential role in the process of verbal communication by shaping the sounds we make when we speak.
Dental polishing is a procedure in dentistry that smooths and refines the surface of a tooth restoration or natural tooth enamel, removing stains and imperfections, through the use of a rotating rubber cup and an abrasive paste.
Dental polishing is a procedure in dentistry that is performed to smooth and clean the surfaces of teeth after professional dental cleaning (prophylaxis), restoration, or other dental treatments. It is usually done using a slow-speed handpiece with a soft, rubber cup attached to it, which holds a polishing paste or a slurry of pumice and water. The polishing paste may contain an abrasive agent, fluoride, or a flavoring agent. The dental professional moves the handpiece in a circular motion over the tooth surface to remove stains, plaque, and minor surface roughness, leaving the teeth smooth and shiny. Dental polishing helps to prevent the buildup of plaque and tartar, reduce the risk of decay and gum disease, and improve the overall oral hygiene and aesthetics of the teeth.
