The cellular immune response to tissue damage and infection requires the recruitment of blood leukocytes. This process is mediated through a classical multistep mechanism, which involves transient rolling on the endothelium and recognition of inflammation followed by extravasation. We have shown, by direct examination of blood monocyte functions in vivo, that a subset of monocytes patrols healthy tissues through long-range crawling on the resting endothelium. This patrolling behavior depended… 

Leukocyte migration into inflamed tissues.

Intravascular Leukocyte Chemotaxis: The Rules of Attraction

To rapidly and efficiently reach their target, specific interactions between circulating leukocytes and vascular endothelium orchestrates leukocyte activation and guides them already within blood vessels to optimal transmigration sites at endothelial loci close to the source of inflammation.

Molecular regulators of leucocyte chemotaxis during inflammation.

The focus of this review is to provide recent insights into molecular mechanisms and cellular processes that mediate leucocyte crawling in blood vessels and tissues during the inflammatory response.

Platelets Guide Leukocytes to Their Sites of Extravasation

The experimental data uncover a platelet-directed, spatiotemporally organized, multicellular crosstalk that is essential for effective trafficking of leukocytes to the site of inflammation.

Monocytes, macrophages, dendritic cells and neutrophils: an update on lifespan kinetics in health and disease

Insight into the kinetic profiles of innate myeloid cells during steady state and pathology will permit the rational development of therapies to boost the production of these cells in times of need or reduce them when detrimental.

How leukocytes cross the vascular endothelium

This Review focuses on recently described mechanisms that control and open exit routes for leukocytes through the endothelial barrier.

Platelet activation attracts a subpopulation of effector monocytes to sites of Leishmania major infection

A new role for platelets in host defense involving the selective recruitment of a subpopulation of effector monocytes from the blood to efficiently kill this intracellular parasite is pointed to.

Interstitial leukocyte migration and immune function

Mechanisms of leukocyte migration and sensing involved in diapedesis, tissue-based interstitial migration and egress, immune cell positioning in inflammation, and emerging therapeutic interference strategies are reviewed.

Peeking into the secret life of neutrophils

A broad overview of the current state of research on neutrophil biology is provided, describing the processes in the typical life cycle of neutrophils, from their first appearance in the bone marrow until their eventual destruction.



Locomotion of monocytes on endothelium is a critical step during extravasation

An essential step is discovered, which is called locomotion, in which the monocyte moves from a site of firm adhesion to the nearest junction to begin diapedesis, which fills a gap in the paradigm of extravasation as a multistep process.

Intraluminal crawling of neutrophils to emigration sites: a molecularly distinct process from adhesion in the recruitment cascade

In vivo results clearly delineate two fundamentally different molecular mechanisms for LFA-1 and Mac-1 in vivo, i.e., LFA–1–dependent adhesion followed by Mac- 1–dependent crawling, and both steps ultimately contribute to efficient emigration out of the vasculature.

Fractalkine and CX3CR1 Mediate a Novel Mechanism of Leukocyte Capture, Firm Adhesion, and Activation under Physiologic Flow

FKN mediated the rapid capture, integrin-independent firm adhesion, and activation of circulating leukocytes under flow, and mediate a novel pathway for leukocyte trafficking.

Inflammatory Chemokine Transport and Presentation in HEV

It is demonstrated that inflamed peripheral tissues project their local chemokine profile to HEVs in draining LNs and thereby exert “remote control” over the composition of leukocyte populations that home to these organs from the blood.

Langerhans cells arise from monocytes in vivo

It is established that CSF-1 receptor–deficient hematopoietic precursors failed to reconstitute the LC pool in inflamed skin and monocytes with high expression of the monocyte marker Gr-1 were specifically recruited to the inflamedskin, proliferated locally and differentiated into LCs.

Subpopulations of Mouse Blood Monocytes Differ in Maturation Stage and Inflammatory Response1

Three subpopulations of mouse blood monocytes can be distinguished by differential expression of Ly-6C, CD43, CD11c, MBR, and CD62L, which differ in maturation stage and capacity to become recruited to inflammatory sites.

Decreased atherosclerosis in CX3CR1-/- mice reveals a role for fractalkine in atherogenesis.

Fractalkine is robustly expressed in lesional smooth muscle cells, but not macrophages, in apoE(-/-) mice on a high-fat diet, providing strong evidence that FK plays a key role in atherogenesis.

Fractalkine in Vascular Biology: From Basic Research to Clinical Disease

New concepts underlying fractalkine-mediated leukocyte migration and tissue damage are examined, focusing primarily on the pathophysiological roles of fractalkin in various clinical conditions, especially in atherosclerosis and vascular injury.
