Subspaces with a common complement in a Banach space [PDF]

open access: yes, 2007
We study the problem of the existence of a common algebraic complement for a pair of closed subspaces of a Banach space. We prove the following two characterizations: (1) The pairs of subspaces of a Banach space with a common complement coincide with ...

Therapeutic Targeting of the Complement System: From Rare Diseases to Pandemics

open access: yesPharmacological Reviews, 2021
The complement system was discovered at the end of the 19th century as a heat-labile plasma component that “complemented” the antibodies in killing microbes, hence the name “complement.” Complement is also part of the innate immune system, protecting the

Complement in the brain [PDF]

open access: yesMolecular Immunology, 2011
The brain is considered to be an immune privileged site, because the blood-brain barrier limits entry of blood borne cells and proteins into the central nervous system (CNS). As a result, the detection and clearance of invading microorganisms and senescent cells as well as surplus neurotransmitters, aged and glycated proteins, in order to maintain a ...
