Twenty cases of tuberculous infection of the hand and the wrist from the division of plastic reconstructive surgery over the past 17 years. There were fourteen males, and six females. The ages of the patients ranged from 10 years to 80 years, with an average age of 50.1 years. The follow-up time was not less than 3 years. The characteristic manifestation of this diseases was insidious onset, and run chronicity. Painful swelling of the wrist and fingers as well as increased sedimentation rate were frequent findings. However, confirmed histopathological diagnosis is essential. Surgical debridement together with triple anti-tuberculous drugs are recommended. Triple drugs therapy should be given for not less than two years to prevent drug resistance and recurrence of the disease.

Unlabelled: Crosstalk between autophagy, host cell death, and inflammatory host responses to bacterial pathogens enables effective innate immune responses that limit bacterial growth while minimizing coincidental host damage. ( ) thwarts innate immune defense mechanisms in alveolar macrophages (AMs) during the initial stages of infection and in recruited bone marrow-derived cells during later stages of infection. However, how protective inflammatory responses are achieved during infection and the variation of the response in different macrophage subtypes remain obscure.

The most abundant envelope glycolipid is trehalose dimycolate (TDM). TDM compromises the host response to mycobacterial species via multiple mechanisms, including inhibition of phagosome maturation.

Recent evidence indicates that PZA acts through disruption of coenzyme A synthesis under conditions that promote cellular stress. In contrast to its bactericidal action , PZA shows weak bacteriostatic activity against in axenic culture.

Introduction: Vaccines against intracellular pathogens like require the induction of effective cell-mediated immunity. Adjuvants primarily enhance antigen-induced adaptive immunity by promoting the activation of antigen-presenting cells (APCs).This study is to develop an adjuvant targeted to dendritic cells (DCs), one of the main APCs, so as to assist in inducing a long-term cellular immune response to protein antigens.

Pathogenic bacteria trigger complex molecular interactions in hosts that are characterized mainly by an increase in reactive oxygen species (ROS) as well as an inflammation-associated response. To counteract oxidative damage, cells respond through protective mechanisms to promote resistance and avoid tissue damage and infection; among these cellular mechanisms the activation or inhibition of the nuclear factor E2-related factor 2 (Nrf2) is frequently observed. The transcription factor Nrf2 is considered the regulator of several hundred cytoprotective and antioxidant genes.
