MFD alters the level of infiltrated immune cells and inflammatory markers in the lungs during chronic Mtb infection. Immunoblot analysis of (a) immune cells (CD4+, CD8+, and F4/80+) and (b) inflammatory markers (IFN gamma, TNF alpha, and IL-6) in the lung lysates of RD-fed and MFD-fed uninfected and infected C57BL/6 mice during chronic (90 DPI) infection.

Background: CD4
Given its critical role in T cell development, CD4 also has diverse immunology-related functions. CD4 acts as a coreceptor with the T-cell receptor (TCR) during T cell activation and thymic differentiation by binding directly to major histocompatibility complex (MHC) class II antigens and associating with the protein tyrosine kinase, Lck (4). This interaction contributes to the formation of the immunological synapse (5). Defects in antigen presentation cause dysfunction of CD4+ T cells and the almost complete loss of MHC II expression on B cells in peripheral blood, as observed in severe combined immunodeficiency (SCID) (6). CD4 also functions as a receptor for the human immunodeficiency virus (HIV) by binding to gp120, the envelope glycoprotein of HIV-1. It has been shown that the V-like domains are critical for binding to gp120 (7). In immune mediated and infectious diseases of the central nervous system, CD4 functions as an indirect mediator of neuronal damage (8).
