TLDR
The results lead to the extablishment of objective criteria to validate intracellular recordings from macrophage and show that slow membrane hyperpolarizations are directly elicited by mechanical stimulation.About:

The increase in the intracellular Ca2+ concentration induced by mechanical stimulation is propagated via release of pyrophosphorylated nucleotides in mammary epithelial cells
TL;DR: It is suggested that the mechanical stimulation results in the release of UTP, UDP and ATP into the extracellular space which mediates induction of the spreading calcium response via P2U-type purinoceptors.
Journal ArticleDOI
Mechanically induced electrical and intracellular calcium responses in normal and cancerous mammary cells
TL;DR: Findings suggested that a certain factor was released from the mechanically stimulated cell to the extracellular space, and this factor induces the increase of [Ca2+]i in surrounding cells.
Journal ArticleDOI
Spontaneous calcium oscillations and mechanically and chemically induced calcium responses in mammary epithelial cells
TL;DR: The results indicate that the sources of Cai2+responses in mammary epithelial cells are intracellular stores, which exchange Ca2+ with the extracellular medium.
Journal ArticleDOI
Does cytosolic free Ca2+ signal neutrophil chemotaxis in response to formylated chemotactic peptide?
TL;DR: The data suggest that neutrophil chemotaxis towards a source of formylated peptide occurs without significant changes in Ca2+ signalling.
Journal ArticleDOI
Phagocytic activity and hyperpolarizing responses in L-strain mouse fibroblasts.
TL;DR: It is concluded that the Ca2+ inflow on the hyperpolarizing membrane responses is closely associated with the phagocytic activity in L cells, probably through activation of the microfilament assembly.

The effect of internal and external potassium concentration on the membrane potential of frog muscle.
TL;DR: The present paper describes experiments in which the membrane potential of frog sartorius muscle was measured in solutions of different potassium content, and in solutions which were designed to alter the inside concentration of potassium keeping the outside concentration constant.
Book ChapterDOI
The regulatory role of macrophages in antigenic stimulation.
TL;DR: The positive immunogenic role of macrophages is related to their capacity to remove extracellular antigen, which might be capable of interacting with and eliminating isolated T or B lymphocytes and retain antigen in lymphoid tissues and promote its necessary meeting with both T and B cells.

Role of Contractile Microfilaments in Macrophage Movement and Endocytosis
TL;DR: One of us has found that the peripheral or cortical cytoplasm of macrophages contains a network of microfilaments, some of which may be inserted into the plasma membrane and bind heavy meromyosin.
