Recessively inherited defects in several COX assembly proteins result in the failure to assemble a functional holoenzyme and underlie a number of mitochondrial respiratory chain disease presentations characterised by isolated COX deficiency.
Horner's syndrome may be present at presentation or develop post-operatively from disruption of the sympathetic chain in the neck[ 4 ].
Tendon pathology and subsequent rehabilitation will vary considerably depending on the site of pathology; stage of the tendinopathy; functional assessment; activity status of the person; contributing issues throughout the kinetic chain; comorbidities; and concurrent presentations.
This approach recognizes that protein subdomains or protein secondary structures are often present at interfaces and serve as organized scaffolds for the presentation of side chain groups that engage the partner protein(s).
It is well known that cathepsin L is involved in the proteolysis of MHC class II-associated invaliant chain (Ii) and the antigen presentation in cortical thymic epithelial cells [29] [31].
Cathepsin S (CatS) distinguishes itself from many other family members with a restricted normal tissue expression, found mainly in lymphatic tissue and cells of monocyte/macrophage lineage, where it plays a key role in MHC class II presentation through invariant chain degradation (Kirchke et al, 1989; Bania et al, 2003).
In particular, clinical features such as high lactate dehydrogenase levels, IgA subtype, presence of extramedullary disease, renal failure, high levels of serum-free light chains or of the serum κ/ λ free light-chain ratio, plasmablastic disease, or presentation as primary plasma cell leukaemia have been identified to confer unfavourable prognostic information (Munshi et al, 2011).
The supramolecular presentation of GAG chains, along with other matrix components, is likely to be functionally important but remains challenging to control and to characterize, both in vivo and in vitro.
Bulky pendant side groups were used to control and modify the degree of chain rotation and therefore the contextual presentation of surface chemistries.
Among other functions, VacA selectively inhibits the invariant chain (Ii -dependent pathway of antIi -dependenttion mediated by the MHC class II and might induce apathways in epithelial cells.
The 3D presentation of the side chain of Arg5 in glycopeptide 2* differs slightly from that found for the other analogues.
