How many courses are required for a history degree?

6 (at least 2 courses from different disciplines and 3 hrs. must be in Historical Perspective)

How many credit hours are required for Cardinal Core?

The Cardinal Core program requires a minimum of 31 credit hours from approved course categories as outlined in the table below. Students must complete a minimum of 12 hours in the Skills courses, a minimum of 19 hours in the Disciplinary Perspectives courses, and within the 31 hours students must accumulate 6 hours in Diversity credit. Academic advisors can guide students in the selection of courses.

Do you have to take one course in the arts and one in the humanities?

Students no longer have to take one course in the Arts and one in the Humanities, but still need to take courses from two different disciplines to fulfill the AH requirement.

Where is CD1 expressed?

CD1 molecules are expressed on thymocytes. They are absent on mature peripheral blood T-cells, but their cytoplasmic expression has been observed in activated T-lymphocytes. High levels of CD1a and less of CD1b and CD1c are present on Langerhans cells [41].

What is CD1 in biology?

CD1 proteins are single-pass transmembrane proteins that have a short intracellular domain. The extracellular portion of CD1 is composed of three domains that mediate antigen binding, whereas specific motifs in the intracellular domain control CD1 trafficking to intracellular compartments (see later discussion). The extracellular domains of CD1 molecules form an antigen-binding groove that is structurally analogous to the peptide-binding groove of the MHC. Consistent with the lipid presentation function of CD1, the antigen-binding groove contains multiple hydrophobic pockets that can accommodate the aliphatic chains of lipid antigens. The three-dimensional structure of mouse CD1266 and human CD1b 265 reveals a complicated network of hydrophobic channels that can accommodate diverse lipids of varying aliphatic chain length (see Fig. 6-6 ). In contrast to the five CD1 isoforms found in humans, mice lack CD1a, CD1b, and CD1c and have a duplicated CD1d gene. This important difference between mice and human CD1 complicates the experimental analysis of CD1 function because the powerful tools of genetically altered mice are not available to analyze the function of CD1a, CD1b, or CD1c.

What is CD1 in T cells?

CD1 plays an important role in presenting mycobacterial lipids to T cells,267 ,268 specifically glycosylated and free mycolic acids and lipoarabinomannan, two major lipid and glycolipid components of the M. tuberculosis cell envelope.

Why are CD1 antigens attractive?

CD1-presented antigens are also attractive vaccine candidates because the limited degree of polymorphisms in the CD1 locus makes it more likely that such antigens would elicit a consistent immune response, even in genetically diverse human populations.

What is the difference between CD1 and HLA?

CD1 genes are MHC-unlinked, i.e. the human CD1 genes are encoded on chromosome 1, while HLA genes are encoded on chromosome 6. Similarly, the mouse CD1 genes are encoded on chromosome 3, whereas MHC genes are mapped to chromosome 17. The intron–exon structure of CD1 genes is similar to that of the MHC class I genes (Figure 1 ).

What are CD1 restricted cells?

CD1-restricted T-lymphocytes fulfil helper and effector functions, and interact with other cell types including macrophages and dendritic cells. In TB most activated CD1-restricted clones respond to many lipid antigens (Table 8.2 ). The effector CD1-restricted cells are of the Th1 type and they produce IFN-γ and TNF-α and lyse M. tuberculosis -infected macrophages in a similar manner to lysis by CD8+ T-lymphocytes. CD1-restricted CD4+ and CD8+ lymphocytes both elaborate granulysin and therefore exhibit direct microbiocidal activity. 29

Which type of antigen is present in CD1?

CD1 molecules present lipid antigen to T cells. The CD1 family of class I MHC–like glycoproteins includes CD1d on the surfaces of DCs and CD1e, which remains in the endoplasmic reticulum. CD1a, CD1b, CD1c, and CD1d-restricted T cells express CD4 or CD8 or lack both CD4 and CD8 (double negative). By contrast, most CD1d-restricted T cells express a semi-invariant TCR and markers of NK cells and are identified as invariant NK T (iNKT) cells.126

What is CD1 in biology?

InterPro. CD1 ( cluster of differentiation 1) is a family of glycoproteins expressed on the surface of various human antigen-presenting cells. They are related to the class I MHC molecules, and are involved in the presentation of lipid antigens to T cells. However their precise function is unknown.

What is CD1 group?

Group 1 CD1 molecules have been shown to present foreign lipid antigens, and specifically a number of mycobacterial cell wall components, to CD1-specific T cells.

What are the two groups of CD1 glycoproteins?

CD1 glycoproteins can be classified primarily into two groups which differ in their lipid anchoring. CD1a, CD1b and CD1c ( group 1 CD1 molecules) are expressed on cells specialized for antigen presentation. CD1d (group 2 CD1) is expressed in a wider variety of cells.

Why is CD1 used in immunohistochemistry?

This often remains true in neoplastic cells from these populations, so that the presence of CD1 antigens can be used in diagnostic immunohistochemistry to identify some thymomas and malignancies arising from T cell precursors.

What is CD1A in lymphoma?

CD1a, in particular, is a specific marker for Langerhans cells, and can therefore also be used in the diagnosis of Langerhans cell histiocytosis. Other conditions that may show CD1 positivity include myeloid leukaemia and some B cell lymphomas.

Do mice have CD1D?

In cows and mice. Mice lack the group 1 CD1 molecules, and instead have 2 copies of CD1d. Thus, mice have been used extensively to characterize the role of CD1d and CD1d-dependent NKT cells in a variety of disease models.

Is CD1 a natural antigen?

The natural antigens of group 2 CD1 are not well characterized, but a synthetic glycolipid, alpha-galactosylceramide, originally isolated from a compound found in a marine sponge, has strong biologic activity.

How are university courses arranged?

The courses are arranged in alphabetical order by course title not by abbreviation. The appearance of a course does not guarantee that the course will be offered ...

Does the appearance of a course guarantee that the course will be offered during the academic year?

The appearance of a course does not guarantee that the course will be offered during the academic year. The University reserves the right to add, modify or withdraw any course or courses without notice.

What is the purpose of the rear lunge?

Exercise 2: The Rear Lunge. Purpose: This exercise promotes balance, opens up the hip and trunk on the side of the lunge and develops leg strength. Starting Position: Straddle stance with hands on hips.

Which counts are the forearms parallel to the ground?

On counts one and three, the forearms are parallel to the ground and slightly higher than the trunk.

How to do count 3?

On count three, round the back slightly while bending forward, keeping the head aligned with the spine and the knees slightly bent. Precautions: This exercise is always performed at a slow cadence. Allowing the knees to go beyond the toes on count one increases stress to the knees. Conditioning Drill 1.
