Death domain-containing receptors of the TNF receptor superfamily (i.e., TNFR1, Fas/CD95/APO-1, and TRAIL-R), Toll-like receptor 3 (TLR3), and TLR4 are the main receptors that trigger necroptosis.

Toll-Like Receptors (TLRs): Structure, Functions, Signaling, and Role of Their Polymorphisms in Colorectal Cancer Susceptibility
https://www.ncbi.nlm.nih.gov/labs/pmc/articles/PMC8452412/
All PRRs are germline-encoded proteins which can recognize wide varieties of alien molecules (e.g., lipid, carbohydrate, peptide, and nucleic acid) commonly found in pathogens but distinct from the host molecules and thus are commonly referred to as PAMPs

Pathogen Associated Molecular Pattern
https://www.sciencedirect.com/topics/medicine-and-dentistry/pathogen-associated-molecular-pattern
Pathogen associated molecular patterns (PAMP) are molecules with conserved motifs that are associated with pathogen infection that serve as ligands for host pattern recognition molecules such as Toll-like receptors.

Mycoplasma Incognitus
Mycoplasma incognitus is an immunomodulatory agent that can alter the immune response by reducing the immune system's ability to produce antibodies by entering into the individual cells of the body where it can lie dormant for 10, 20, or 30 years. If a trauma occurs M. incognitus can become triggered and start invading and destroying certain cells, depending on the individual's genetic predisposition.
M.incognitus has the ability to alter red blood cells so that they swell and therefore cannot be compressed and passed through the capillaries.
The mycoplasma is able to stimulate or suppress lymphocytes in a polyclonal manner both in vitro and in vivo, and modulate the activities of monocytes, macrophages, and NK cells.
The lipid-associated membrane proteins of Mycoplasma incognitus can activate the long terminal repeats of HIV through toll-like receptors.

lectin pathway is activated is through mannose-binding lectin protein. MBL binds to carbohydrates (to be specific, D-mannose and L-fucose residues) found on the surfaces of many pathogens.
MBL has been shown to bind to:
yeasts such as Candida albicans
viruses such as HIV and influenza A
many bacteria, including Salmonella and Streptococci
parasites like Leishmania
SARS-CoV-2
