As is the case with differentiation, phenotype, and function of alveolar macrophages, inflammation regulates macrophage cell fate. Toxicity in internal organs. Chronic Inflammation Inflammation of prolonged duration (weeks or months) » Active inflammation, tissue destruction, and attempts at repair are proceeding simultaneously May follow acute inflammation or begin insidiously and often asymptomatically » Persistent infections, exposure to toxic agents such as silica (silicosis), or by autoimmunity Disruption of the adherent mucous layer. Spinal glial activation in a new rat model of bone cancer pain produced by prostate cancer cell inoculation of the tibia. GO can result in acute inflammation response and chronic injury by interfering with the normal physiological functions of important organs [32, 81].Oral gavage experiments did not show detectable absorption of GO through the gastrointestinal tract [].Interesting, a low dose of GO caused serious damage to the gastrointestinal tract after maternal mice drank a GO . Inflammation evolved as an acute response that is quickly suppressed upon restoration of tissue homeostasis; failure to efficiently resolve inflammatory insults can have serious consequences for tissue maintenance and function. Differential local tissue permissiveness influences the final fate of GPR17-expressing oligodendrocyte precursors in two distinct models of demyelination.

Acute infection with H.pylori : produce neutrophilic inflammation of the mucosa II- Decrease protective factors 3 . Inflammation also affects immune surveillance and responses to therapy. Neutrophils first differentiate in the bone marrow through progenitor intermediaries before entering the blood, in a process that gauges the extramedullary pool size. Fibrinoid Necrosis and Inflammation of Vessel Wall. • Study whether and how mitochondrial dysfunction affects lung progenitor cell fate, maintenance and regeneration capacity after acute lung injury. Inflammation Host response to get rid of - Damaged - Necrotic tissues - Foreign invaders (microbes) Protective response Acute or chronic Acute- Rapid in onset (typically minutes) - Short duration, lasting for hours or a few days Two response - reaction subsides - can progress to a chronic phase. - the incidence of chronic rejection may be increasing. The ensuing hyperemia, leak of plasma proteins, and recruitment of leukocytes serve a number of useful functions in host defense and tissue repair. Chronic inflammation represents a long-term reaction to an inflammatory stimulus characterized by continued recruitment of mononuclear leukocytes (monocytes and lymphocytes) accompanied by tissue injury due to the sustained inflammatory response.

The resolution of inflammation is an active, rather than passive process. Subacute inflammation is the period between acute and chronic inflammation and may last 2 to 6 weeks. Although many cells are involved in chronic inflammation, macrophages seem to play an important role in impaired muscle regeneration since these cells are associated with skeletal muscle stem cell (namely, satellite cells) activation and fibro-adipogenic progenitor cell (FAP) survival.
