Menopause leads to elevated expression of macrophage-associated genes in the aging frontal cortex: rat and human studies identify strikingly similar changes. [PDF]
, 2012 BACKGROUND The intricate interactions between the immune, endocrine and central nervous systems shape the innate immune response of the brain. We have previously shown that estradiol suppresses expression of immune genes in the frontal cortex of ...

Receptors for Complement on Langerhans Cells
Journal of Investigative Dermatology, 1980 A population of guinea pig epidermal cells, identified as Langerhans cells, formed rosettes with sheep erythrocytes coated with IgM immunoglobulin and C3b (EAC1-3b) but not with intermediates carrying only C1, C14b, or C14b2a. These findings were unusual since most other cells expressing C3b receptors also express C4b receptors.

A promising approach for the real-time quantification of cytosolic protein-protein interactions in living cells [PDF]
, 2020 In recent years, cell-based assays have been frequently used in molecular interaction analysis. Cell-based assays complement traditional biochemical and biophysical methods, as they allow for molecular interaction analysis, mode of action studies and even drug screening processes to be performed under physiologically relevant conditions.

Yersinia enterocolitica serum resistance proteins YadA and ail bind the complement regulator C4b-binding protein. [PDF]
PLoS Pathogens, 2008 Many pathogens are equipped with factors providing resistance against the bactericidal action of complement. Yersinia enterocolitica, a Gram-negative enteric pathogen with invasive properties, efficiently resists the deleterious action of human ...

PLoS ONE, 2014 Type 2 diabetes patients (DM2) have a higher risk of tuberculosis (TB) that may be attributed to functional defects in their mononuclear phagocytes given the critical role of these cells in Mycobacterium tuberculosis containment.

Large number of receptors may reduce cellular response time variation [PDF]
Physical biology 10 (3), 035008, 2013, 2012 Cells often have tens of thousands of receptors, even though only a few activated receptors can trigger full cellular responses. Reasons for the overabundance of receptors remain unclear. We suggest that, in certain conditions, the large number of receptors results in a competition among receptors to be the first to activate the cell.

Complement Activation Contributes to Severe Acute Respiratory Syndrome Coronavirus Pathogenesis
mBio, 2018 The complement system is a critical part of host defense to many bacterial, viral, and fungal infections. It works alongside pattern recognition receptors to stimulate host defense systems in advance of activation of the adaptive immune response. In this

Phagocytosis of Legionella pneumophila is mediated by human monocyte complement receptors. [PDF]
, 1987 We have examined receptors mediating phagocytosis of the intracellular bacterial pathogen, Legionella pneumophila. Three mAbs against the type 3 complement receptor (CR3), which recognizes C3bi, inhibit adherence of L.

Unraveling Mycobacterium tuberculosis acid resistance and pH homeostasis mechanisms
FEBS Letters, EarlyView.Mycobacterium tuberculosis exhibits a remarkable resilience to acid stress. In this Review, we discuss some of the molecular mechanisms and metabolic pathways used by the tubercle bacilli to adapt and resist host‐mediated acid stress. Mycobacterium tuberculosis (Mtb) is a successful pathogen that has developed a variety of strategies to survive and ...
