Homorthodes furfurata, the northern scurfy Quaker moth or scurfy Quaker moth, is a species of moth in the family Noctuidae (owlet moths). It was described by Augustus Radcliffe Grote in 1874 and is found in forest habitats in North America. Its range extends across the continent, to south-eastern Canada, Massachusetts, New York, and Mississippi. In the west it ranges south to California, Arizona, New Mexico and Texas.

Many patients with IPEX have mutations in the DNA-binding forkhead domain of FOXP3. In mice, a Foxp3 mutation (a frameshift mutation that result in protein lacking the forkhead domain) is responsible for 'Scurfy', an X-linked recessive mouse mutant that results in lethality in hemizygous males 16 to 25 days after birth. These mice have overproliferation of CD4+ T-lymphocytes, extensive multiorgan infiltration, and elevation of numerous cytokines. This phenotype is similar to those that lack expression of CTLA-4, TGF-β, human disease IPEX, or deletion of the Foxp3 gene in mice ("scurfy mice").

Most individuals have other autoimmune phenomena including Coombs-positive hemolytic anemia, autoimmune thrombocytopenia, autoimmune neutropenia, and tubular nephropathy. The majority of affected males die within the first year of life of either metabolic derangements or sepsis. An analogous disease is also observed in a spontaneous Foxp3-mutant mouse known as "scurfy".

Its surface texture is smooth to slightly scurfy, and it is often whitish at its base. The flesh of the mushroom lacks any distinctive taste or odor. It is yellowish with orange tinges, with reddish color near the cap cuticle. Alan Bessette and colleagues, in their 2012 monograph on eastern North American waxcap mushrooms, note that the mushroom is "reported to be edible".

The pathology observed in scurfy mice seems to result from an inability to properly regulate CD4+ T-cell activity. In mice overexpressing the Foxp3 gene, fewer T cells are observed. The remaining T cells have poor proliferative and cytolytic responses and poor interleukin-2 production, although thymic development appears normal. Histologic analysis indicates that peripheral lymphoid organs, particularly lymph nodes, lack the proper number of cells.

|
A stem, if present, may be up to long and scurfy—covered with small flakes or scales. The texture of the flesh may range from pliable to brittle. This fungus does not undergo any color changes upon bruising or injury, however, a 10% solution of FeSO4 (a chemical test known as "iron salts") applied to the flesh will turn it green. In deposit, the spores are white.

There is as well a special mouse model simulating the development and progression of the IPEX syndrome. The model mice are called "scurfy mice" and they have had 2 base pairs inserted within the Foxp3 gene. Consequently, this leads to a frameshift and the expressed protein is truncated, causing the same effects as FOXP3 mutation in humans. The mice suffer from enlarged spleen and lymph nodes, redness in eyes, and skin abnormalities.

Zamia furfuracea is a cycad native to southeastern Veracruz state in eastern Mexico. Although not a palm tree (Arecaceae), its growth habit is superficially similar to a palm; therefore it is commonly known as cardboard palm or cardboard cycad. Other names include cardboard plant, cardboard sago, Jamaican sago, and Mexican cycad (from Mexican Spanish Cícada Mexicana). The plant's binomial name comes from the Latin zamia, for "pine nut", and furfuracea, meaning "mealy" or "scurfy".

It is a high-mountain species occurring in northern and central Taiwan at elevations between 2400 and 3800 m in association with other temperate plants, dominantly conifers, including Juniperus formosana var. formosana, Tsuga formosana, and Juniperus morrisonicola. Taiwan fir is a small to medium-sized tree sometimes reaching a height of 35 m and trunk diameter of 1 m. Initially, the bark is scurfy or scaly, lenticellate, later detaching in elongated plates.

Since the beginning of 2016, he has been Research Director at the Parker Institute for Cancer Immunotherapy in San Francisco. Ramsdell and team identified Forkhead Box Protein P3 (FOXP3) in scurfy mice and in children with IPEX syndrome, a severe autoimmune disease. They further determined that FOXP3 plays a crucial role in the development of regulatory T cells. In 2017, Ramsdell received, jointly with Shimon Sakaguchi and Alexander Rudensky, the Crafoord Prize for research in polyarthritis.

Atriplex patula, female flower with bracteoles and seed The species in genus Atriplex are annual or perennial herbs, subshrubs, or shrubs. The plants are often covered with bladderlike hairs, that later collapse and form a silvery, scurfy or mealy surface, rarely with elongate trichomes. The alternate or rarely opposite leaves are petiolate or sessile, often persistent or tardily deciduous. The flat or slightly fleshy leaf blades are either entire, or serrate, or lobed and very variable in shape.

Mature buds are scurfy, oval to pear-shaped, greenish to brown or cream-coloured, long, wide with a conical, rounded or flattened operculum. Flowering occurs between March and October and the flowers are white. The fruit is a woody urn-shaped capsule long and wide on a pedicel long and with the valves enclosed in the fruit.

The fruit body is in diameter from tip to tip when expanded. The exoperidium is thick, and the rays are typically areolate (divided into small areas by cracks and crevices) on the upper surface, and are dark grey to black. The spore case is sessile (lacking a stalk), light gray to tan color and broad with a felt-like or scurfy (coated with loose scaly crust) surface; the top of the spore case is opened by an irregular slit, tear or pore. The interior of the spore case, the gleba, is white and solid when young, and divided into oval locules—a characteristic that helps to distinguish it from Geastrum.
