Identification of an alternative G{alpha}q-dependent chemokine receptor signal transduction pathway in dendritic cells and granulocytes [PDF]
, 2007 CD38 controls the chemotaxis of leukocytes to some, but not all, chemokines, suggesting that chemokine receptor signaling in leukocytes is more diverse than previously appreciated.

The alternative complement pathway revisited [PDF]
Journal of Cellular and Molecular Medicine, 2008 Introduction Methods to study and modify the alternative pathway Influence of AP amplification on the effect of specific activation of the other initial pathways Properdin Influence of AP in deficiency states Complement in sepsis Concluding remarks AbstractAlternative pathway amplification plays a major role for the final effect of initial specific ...

The "backdoor pathway" of androgen synthesis in human male sexual development. [PDF]
, 2019 Mammalian sex determination (male versus female) is largely controlled by genes, whereas sex differentiation (development of reproductive structures) is largely controlled by hormones. Work in the 20th century indicated that female external anatomy was a

Nitrogen deprivation induces cross-tolerance of Poa annua callus to salt stress
Biologia Plantarum, 2016 Alternative respiration pathway (AP) is an important pathway which can be induced by environment stresses in plants. In the present study, we show a new mechanism involving the AP in nitrogen deprivation-induced tolerance of Poa annua callus to salt ...

Frontiers in Immunology, 2022 The complement system is a part of the innate immune system, where it labels intruding pathogens as well as dying host cells for clearance. If complement regulation is compromised, the system may contribute to pathogenesis.

Role of Pneumococcal NanA Neuraminidase Activity in Peripheral Blood
Frontiers in Cellular and Infection Microbiology, 2019 The most frequent form of hemolytic-uremic syndrome (HUS) is associated with infections caused by Shiga-like toxin-producing Enterohaemorrhagic Escherichia coli (STEC). In rarer cases HUS can be triggered by Streptococcus pneumoniae.

Searching for pathways involving dressed states in optimal control theory [PDF]
, 2011 Selective population of dressed states has been proposed as an alternative control pathway in molecular reaction dynamics [Wollenhaupt et al., J. Photochem. Photobiol. A: Chem., 2006, 180, 248].

Hijacking Factor H for Complement Immune Evasion
Frontiers in Immunology, 2021 The complement system is an essential player in innate and adaptive immunity. It consists of three pathways (alternative, classical, and lectin) that initiate either spontaneously (alternative) or in response to danger (all pathways). Complement leads to

The Alternative Choice of Constitutive Exons throughout Evolution [PDF]
, 2007 Alternative cassette exons are known to originate from two processes exonization of intronic sequences and exon shuffling. Herein, we suggest an additional mechanism by which constitutively spliced exons become alternative cassette exons during evolution.

Arginyltransferase, Its Specificity, Putative Substrates, Bidirectional Promoter, and Splicing-derived Isoforms [PDF]
, 2006 Substrates of the N-end rule pathway include proteins with destabilizing N-terminal residues. Three of them, Asp, Glu, and (oxidized) Cys, function through their conjugation to Arg, one of destabilizing N-terminal residues that are recognized directly by
